There is milk in the body of the cow; the milk has ghee (clarified butter) latent in it. But the cow cannot derive any strength through that latent ghee. The milk has to be taken out of the animal, boiled, and a little sour curd poured into it in order to curdle it. Then, when the milk is transformed into curds, it has to be churned and the butter separated and rolled. After this, the butter has to be melted and clarified, only then can ghee be obtained. The ghee thus prepared can be fed to the cow which would make it stronger. So too, God is omnipresent. Yet, He is not easily available or perceivable to individuals unless they undertake the required sadhana (spiritual practices).

– Sathya Sai Vahini, Chap 12: "Values in Later Texts"

There is only one God; He is Omnipresent. – Baba
