Why do householders need to do both karma phala tyaga and karma samnyasa?

[Shri Ganesh V asked: Padanamaskaram Swamiji, You have clearly said that the real yagna is to feed the human incarnation of God. That is real yagna is karma phala tyaga and for sanyasis karma samnyasa. In the light of the above meaning of Yagna, why is it necessary for Grihastas to do both? What is the consequence if Grihastas don’t perform Yagna? At Your divine feet , Ganesh V]

Swami replied:- I am answering the same question again and again. Householder (Gṛhastha) is not only capable of doing the physical service (Karma Saṃnyāsa), but also capable of doing the sacrifice of fruit of work (Karma Phala Tyāga). A saint begging for food is incapable of doing Karma Phala Tyāga and can only do Karma Saṃnyāsa. Apart from the human incarnation of God, the service and sacrifice must be done to the lowest layer of poor people called beggars.
