Śrī brahma-saṁhitā 5.61

In order to strike at the root of this misgiving the Supreme Lord says, “This world subsists by the constant performance of certain activities. Fill all these activities with meditation of Me. This will destroy the quality that makes those activities appear as acts done by you. They will then be of the nature of My service (bhakti).

“Mankind live by the threefold activities of body, mind and society. Eating, seating, walking, resting, sleeping, cleansing the body. covering the body. etc., are the various bodily activities; thinking, recollecting, retaining an impression, becoming aware of an entity. feeling pleasure and pain, etc., are the mental feats; marrying, practicing reciprocal relationship between the king and subject, practicing brotherhood, attending at sacrificial meetings, offering oblations, digging wells, tanks, etc., for the benefit of the people, maintaining one’s relations, practicing hospitality. observing proper civic conduct, showing due respect to others are the various social activities. When these acts are performed for one’s selfish enjoyment, they are called karma-kāṇḍa; when the desire for attainment of freedom from activity by knowledge underlies these actions, they are termed jñāna-yoga or karma-yoga. And when these activities are managed to be performed in this way that is conducive to our endeavor for attainment of bhakti they are called jñāna-bhakta-yoga, i.e., the subsidiary devotional practices. But only those activities that are characterized by the principle of pure worship are called bhakti proper. My meditation is practiced in every act when bhakti proper is practiced in due time while performing the subsidiary devotional activities in one’s intercourse with the ungodly people of this world. In such position, a jīva does not become apathetic to Godhead even by performing those worldly activities. This constitutes the practice of looking inwards, i.e., turning towards one’s real self, vide Īśopaniṣad-
