7.36.19

matpūjākoṭiphaladaṃ sakṛnmajjñānino'rcanam |
kulaṃ pavitraṃ tasyāsti jananī kṛtakṛtyakā ||

The blessed man who worships once My Jñânî, gets Koti times the fruit of worshipping Me. His family is rendered pure and his mother becomes blessed. He whose heart is diluted in the all-pervading Brahma Consciousness, purifies this whole world. There is no doubt in this.
