18.51 बुद्ध्या with an intellect? विशुद्धया pure? युक्तः endowed? धृत्या by firmness? आत्मानम् the self? नियम्य controlling? च and? शब्दादीन् sound and other? विषयान् senseobjects? त्यक्त्वा relinishing? रागद्वेषौ attraction and hatred? व्युदस्य abandoning? च and.Commentary The lower self should be controlled with firmness by the Self of pure intellect. The turbulent senses and the mind should be subdued with the help of the pure intellect or reason. Pure reason is a great power. Whenever the senses raise their heads and hiss? they should be hammered by the powerful rod of pure intellect or reason. Reason is the faculty of determination.Pure intellect The intellect that is free from lust? anger? greed? pride? doubt? misconception? etc. It is like a clear mirror. A pure intellect is Brahman Itself. It can be easily merged in Brahman. When the pure intellect is merged in Brahman? the reflected intelligence? Chidabhasa or Jiva? is also absorbed in Brahman. The Jiva becomes identical with Brahman? just as the ether in the pot becomes one with the universal ether when the pot is broken.The self The aggregate of the body and the senses.The aspirant withdraws the senses from their respective objects again and again through the repeated practice of Pratyahara (abstraction) and Dama (selfrestraint). Gradually the senses are fixed in the Self. Their outgoing tendencies are totally curbed. The aspirant attains supreme control of the senses by constant meditation? by the practice of dispassion he coners Raga (attachment)? and through the practice of pure love or cosmic love or divine Preme he coners hatred.He abandons all luxuries. He keeps only those objects which are necessary for the bare maintenance of the body. He has neither attachment nor hatred even for those objects which are necessary for that purpose.

When one is purified by intelligence, he keeps himself in the mode of goodness. Thus one becomes the controller of the mind and is always in trance. He is not attached to the objects of sense gratification, and he is free from attachment and hatred in his activities. Such a detached person naturally prefers to live in a secluded place, he does not eat more than what he requires, and he controls the activities of his body and mind. He has no false ego because he does not accept the body as himself. Nor has he a desire to make the body fat and strong by accepting so many material things. Because he has no bodily concept of life, he is not falsely proud. He is satisfied with everything that is offered to him by the grace of the Lord, and he is never angry in the absence of sense gratification. Nor does he endeavor to acquire sense objects. Thus when he is completely free from false ego, he becomes nonattached to all material things, and that is the stage of self-realization of Brahman. That stage is called the brahma-bhūta stage. When one is free from the material conception of life, he becomes peaceful and cannot be agitated. This is described in Bhagavad-gītā (2.70) : āpūryamāṇam acala-pratiṣṭhaṁ samudram āpaḥ praviśanti yadvat tadvat kāmā yaṁ praviśanti sarve sa śāntim āpnoti na kāma-kāmī “A person who is not disturbed by the incessant flow of desires – that enter like rivers into the ocean, which is ever being filled but is always still – can alone achieve peace, and not the man who strives to satisfy such desires.”
