In plain words
Sai Rāma has incarnated to teach this principle of Satya and Prema. I have come only to show the God who is present wherever you look. If He is present wherever you look, why should Sai come? So they think. But there must be one who tells it, surely.
The lamp-bowl, the oil, the wick are there; will the light of the lamp arise? With flowers, needle and thread at hand, will the garland make itself?
There has to be one who sews it, surely! In the same way, one must come in order to tell that God is present wherever you look.
With a driver there to drive the running train, with a master there over the automatic light, must there not be One to create the world!
To run a train there must be a driver, surely. There must be one who controls the automatic light, surely! In the same way, there must be One to create the world. One is needed to tell that He is present wherever you look. All the Avatāras are the very ones who come to tell it in this way. The Avatāras must come not merely to tell it, but to share their Prema with all. But you receive only as much as the vessel of your heart can hold. Through darśana, sparśana and sambhāṣaṇa you must make your vessel bigger. The bigger the vessel you take, the more amṛta you receive.
