In plain words
For those who say He is, He is, He is; for those who say He is not, He is not, He is not: as long as one says He is not, He stays as though He were not. The moment he thought, He is here, Rāma was caught. Hiraṇyakaśipu searched the whole world. But He was not to be seen. The reason: he searched convinced that Nārāyaṇa was not there. Prahlāda held the faith, ‘Doubt not that He is here and not there; the bearer of the discus is everywhere; wherever you search, there He is.’ So wherever He was sought, there He was caught. In this, the inner feeling is what matters most.
Say No to the one who says No, say Yes to the one who says Yes. No and Yes are for our mouths alone, but for Sai all is SSS.
