Bhagavad-gita As It Is

by A.C. Bhaktivedanta

By performance of yajñas, all activities become purified, as it is stated in the Vedas ( Chāndogya Upaniṣad 7.26.2): āhāra-śuddhau sattva-śuddhiḥ sattva-śuddhau dhruvā smṛtiḥ smṛti-lambhe sarva-granthīnāṁ vipramokṣaḥ. By performance of yajña one’s eatables become sanctified, and by eating sanctified foodstuffs one’s very existence becomes purified; by the purification of existence finer tissues in the memory become sanctified, and when memory is sanctified one can think of the path of liberation, and all these combined together lead to Kṛṣṇa consciousness, the great necessity of present-day society.

How much it is imp to eat food cooked and offered by devotees only.
