A Momentary Doubt: "Then is practice not necessary?" Other means (sacrificial acts and ritual) are futile—because once the impediments to knowledge (those barriers that obstruct the flowering of true knowledge even after it has arisen—if the knowledge of Brahman-Self obtained from scripture does not manifest in one's life, it is because of these impediments) are removed, the bonds themselves naturally fall away. Consider: the sun exists, and therefore light exists; yet clouds (impediments) veil that light, so we do not receive its full radiance. Once the clouds pass, light returns. Here, the decisive key is unwavering knowledge born from the testimony of scripture. Though many texts elaborate at great length on hearing, reflection, and meditation, this matter is being emphasized: when knowledge becomes clear, nothing more needs to be added. Scripture typically speaks of three kinds of impediments—doubt (Saṁśaya): "Am I truly Brahman?" "Is what the scriptures tell us absolutely true?"—such hesitation weakens knowledge. Misapprehension (Viparyaya): seeing things backwards; as when—"I am the body," "I am the sufferer," "I am the agent." Even after knowing the truth, the old false perspective persists. Habit and conditioning (Pratyaya / Ādhyāsika Vāsanā): through the force of countless lifetimes, one reverts to old patterns of thought and action. When anger arises, the mind instantly believes, "I have been insulted"—though scripture declares, 'The Self is never insulted.' The consequence of impediments to knowledge is this: knowledge may arise yet bear no fruit. One may hear the scriptures proclaim the non-duality of Brahman-Self, may come to know it, yet still experience in one's own life the sorrow and joy, attachment and fear of former times. This is why one thinks: "I know it, yet it does not come alive in experience." How are these impediments removed? According to scripture—hearing (listening, study) → grasping the teaching of scripture clearly. Reflection (reasoning) → dispelling doubt through logic. Meditation (contemplation and insight) → gradually effacing old habits and conditioning—through these three processes the impediments to knowledge dissolve, and knowledge becomes efficacious. Impediments to knowledge = such obstacles as prevent true knowledge, even after it has arisen, from becoming effective. Their root lies in doubt, misapprehension, and old conditioning. When these are cleared, knowledge shines forth in its full luminescence—only then does one attain true liberation (moksha). One who has truly realized the non-duality of Brahman-Self will no longer bear the qualities of bondage as before. If bondage remains in someone, then the realization of non-duality has not truly occurred—therefore the objection that 'further means are needed' is itself incoherent. A Rebuttal: Though true knowledge is obtained through the means of valid knowledge, in some cases erroneous cognitions do not immediately vanish. They persist due to special causes—as when one sees two moons (illusion born of eye defect) or confuses directions (mistaking one direction for another). Though the truth about the moon and directions may be clearly known through the testimony of a reliable observer, the illusion can linger for some time. Similarly, one who has already realized through the scriptures (which are free from doubt) the truth of the Self may still experience the persistence of illusion due to the powerful, deeply rooted conditioning formed by repeatedly accumulated false knowledge from ages past. Something else is needed to overcome this. And that "something else" is—repeated contemplation and meditation on true knowledge (nididhyasana); sacrificial acts and the like (which rest on the authority of scripture) also serve this purpose. Repeated contemplation-meditation (nididhyasana) works—by strengthening the impressions of true knowledge and by suppressing the impressions of previous false knowledge. Likewise, ritual acts and similar practices also perform their function in an imperceptible way. Some hold that they work by destroying impurity in the form of inauspiciousness and sin, which is the opposite of all good. For when one performs obligatory rites, the inauspicious is destroyed. Some might object—very well, let the illusion persist; but has there not been certain knowledge of the truth through the valid means of knowledge?
# On Knowledge and Liberation
Man acts according to the truth as he knows it; and therefore, for one who has realized the truth of the self, no practice of action—whether good or evil—is acceptable.
To this we reply: Although true knowledge has arisen, so long as the impression of that knowledge does not become strong, and the impression of erroneous knowledge repeated from time immemorial remains dominant, true knowledge cannot begin to work. We see this in the case of one immersed in illusory knowledge of some object or reality—merely knowing it is not sufficient, for its correct effect does not dispel the delusion at once.
Consider, for instance, a man afflicted with disorientation of direction. Though he hears the correct direction from a reliable person, if he does not retain that instruction repeatedly in his mind, he is seen to walk in the wrong path as before. Similarly, when a rope appears as a snake through delusion—though later one knows it is a rope, if one does not contemplate and dwell upon that truth, the fear persists. Therefore, although true knowledge arises from an infallible means of valid knowledge, it is essential to meditate and reflect repeatedly upon that truth in order to weaken or destroy the powerful impression of erroneous knowledge accumulated from beginningless time. This is why the scriptures declare: “One must reflect upon the self; one must meditate upon it” (*Brhadaranyaka Upanishad*, 2.4.5). Along with this, other means have also been prescribed—such as restraint of mind, restraint of the senses, celibacy, sacrifice, and the like. Otherwise, why would there be any need for the scriptures to offer instruction concerning these things?
An objection may arise: True knowledge of reality arises from the word-testimony of scripture only when it is joined with specific means such as celibacy. But this reasoning is flawed. Knowledge arises solely from word-testimony. The word-testimony used for the purpose of revealing truth is capable of revealing it without any special means. And that knowledge is free from doubt, certain. Were it otherwise, we could not even attain knowledge of the means prescribed in scripture itself.
Consider actors on a stage or in a film. The spectators know they are performing; yet they experience grief, fear, and such emotions as if everything were real. Again, though one knows with certainty that sugar is sweet, if someone’s tongue is affected by a disorder of bile, sugar tastes bitter to him; and he spits it out, believing it truly bitter. Just so, even one who has known without doubt the non-duality of Brahman and the self requires further help to dispel the continuity of delusion. That help consists in meditating and reflecting repeatedly upon the truth-knowledge.
When we consider the nature of liberation, liberation or moksha is not a newly created result; for it is truly the eternal nature of the self itself. Thus when knowledge arises, the manifestation of truth that occurs—that itself is liberation. As to auxiliary means: just as liberation through knowledge is no new creation, so too through auxiliary means such as sacrifice, oblation, and worship, liberation cannot be made into something else; that is, these cannot bring liberation.
Scripture declares: “Through knowledge, liberation”; this means liberation is obtained through knowledge alone, not through anything else. What knowledge? By this knowledge is meant supreme direct intuitive knowledge. And that direct knowledge is born through the perfection of deep reflection (*manana*) and meditation (*nididhyasana*). In other words, knowledge arises from word-testimony, the words of scripture. Therefore, knowledge born of word-testimony is the true cause; from it, the subsequent direct knowledge is gradually revealed. Liberation is no newly created result; it is the eternal nature of the self revealed through knowledge. Ritual action does not bestow liberation.
The scriptural utterance thus points to direct knowledge consolidated through reflection and meditation. Therefore, the root cause of liberation is knowledge born of textual testimony—it alone unlocks the door to freedom.
Let me offer an example. In darkness, you mistook a rope for a snake. Fear arose, agitation seized you, panic sent you running. This fear itself was bondage. Suddenly, light blazed forth—you saw, “Why, it is merely a rope, not a snake at all!” In that instant, fear and agitation dissolved utterly. The vanishing of this fear is liberation itself (mokṣa). Yet mark this well—no new “rope” came into being. The rope was always there; only false perception, shrouded in ignorance and habit, had concealed it. When light broke forth, truth stood revealed.
Earlier it was said that the various scriptural injunctions—rituals, sacrifices, and other ordinances—do indeed bear their own fruits, but they render a person fit for knowledge. The saying goes: one who has discharged the three debts is then eligible for knowledge. But this notion, as a universal principle, is not entirely true. For the scriptures speak of different stages of life (āśrama) separately and distinctly. As in the Gautama Dharmasūtra (1.3.1): “For him there are many stages of life, according to some.” And again: “Let a man dwell in that āśrama which he chooses.”
What are the three debts?
(a) The debt to the sages (ṛṣi-ṛṇa)—meaning: obligation to the ancient seers. The reason: they preserved the Vedas and knowledge for us. The way to repay: the study of Vedas (both learning and teaching), the cultivation of scriptures, and imparting education.
(b) The debt to the gods (deva-ṛṇa)—meaning: obligation to the divine powers. The reason: they sustain nature and the cosmic order, maintain the balance of existence. The way to repay: sacrifice, oblation, worship, prayer; especially the daily fire-rite (agnihotra), the new and full-moon sacrifices (darśa-pūrṇamāsa), the first-fruit offering (āgrayaṇīṣṭi), the soma sacrifice (agniṣṭoma) and other Vedic rituals.
(c) The debt to the ancestors (pitṛ-ṛṇa)—meaning: obligation to one’s forebears. The reason: they gave us our lineage and our very life. The way to repay: ancestral rites (pitṛ-yajña), funeral offerings (śrāddha), the begetting and nurturing of children, the preservation of family and lineage.
In Vedic society, the understanding was this: a person, from the moment of birth, inherits the burden of these three debts. Unless one discharges them, life’s duties remain incomplete. Thus the primary responsibility of the householder is the repayment of these debts. The discharge of the debt to sages, to gods, and to ancestors equals the fulfillment of duty. Should one neglect these duties, a residue of guilt accumulates in the householder’s heart, and this very guilt becomes an impediment to knowledge. The scriptures declare: if one is a householder and enters the path of renunciation or knowledge without fulfilling these three debts, one is consumed by sin. For when duty is abandoned and the path of liberation is entered directly, the weight of “undischarged obligation” becomes a barrier on that path.
Yet certain heterodox scriptural views present a different picture. The Jābāla Upaniṣad (4) states: “Otherwise (if the opportunity arises), renunciation may be adopted even from the stage of studenthood.” The Kauṣītaki Upaniṣad (2.4) says: the ancient sages surely did not perform the daily fire-rite after attaining knowledge (having already done so). The Bṛhadāraṇyaka (4.4.22) asks: “What shall we gain through a son? Why then perform sacrifice?”—that is, the obligation to discharge the three debts is not binding upon all in the same measure. The repayment of the three debts constitutes the duty of the householder; their fulfillment clears from his heart any sense of guilt or incompleteness of duty, allowing knowledge to emerge easily. Yet not all are bound by the same rule. For some, the performance of sacrifice, ancestral rites, and duty is essential; for others, renunciation and the direct path of knowledge are sanctioned.
