He from whom all works, all desires, all sweet odours and tastes proceed, who embraces all this, who never speaks and who is never surprised, he, my self within the heart, is that Brahman (n.) When I shall have departed from hence, I shall obtain him (that Self). He who has this faith has no doubt; thus said Sândilya, yea, thus he said.

In plain words: The teacher Sandilya says that this Self inside my heart, the source of everything, is Brahman itself. When I die, I will go to it. A person who truly trusts this has no doubt left.
