When I visited Prema Sai for the first few times, I decided to repeat Gayatri Mantra as much as possible in his divine presence. Once I was practicing in my mind sitting on the floor, and the divine child was playing alongside. Suddenly, Prema Sai looked at me and gestured that I should stop repeating Gayatri Mantra. In simple English words, he said that he knew that I was practicing exactly Gayatri Mantra and asked me to stop it for that day.
I was surprised that the divine boy knew that I was repeating precisely Gayatri Mantra. For that day I stopped chanting. Naturally the next day I continued my practice. I realized that it was a great blessing, Lord Sai always knows what and how we practice.
