Sri Vasista
O Rama, a person who knows the reality should keep his mind (in the following state) when he is engaged in activities in the world, mixing with people of all types and in association with many kinds of institutions.
-7 He should not be attached to actions. He should not be involved with things and thoughts. He should not be worried about anything around him (be it earth, sky or quarters), neither external or internal. He should not be united with the movements of the senses, not even with the vital airs. He should not be worried about his face, nose or the space between the eyebrows. He should not be united with darkness, or light or waking or deep sleep. Neither steadiness nor movement should engage his attention. He should not be attentive to sensual activities, nor should he be concerned with delusion or joy and not even time should be of his interest.
He should be reposed in the absolute consciousness. Even a little dependence on external objects will lead to weakness and debility. Always mind should abide in the essential nature of Self.
-11 Devoid of attachment, when a person is established in Brahman, realizing that he is really non existent, it does not matter whether he is engaged in worldly activities or not. He will not have any relationship with the fruits of action. If he abandons involvement in the outer world, he abides in perfect peace in the majesty of consciousness. He will be like an effulgent diamond in Self.
O Rama, with constant awareness of Self and having attained Nirvana a being does not get touched or stained by activity because of his lack of interest in them. With such detachment he does not care for the fruits of action. He merely tolerates the burden of his body till the end of his destiny.
