Education in England
This afternoon I was doing japa as usual and dropped off to sleep. Then I saw a curious dream.... I sang and the song was on Shiva, and was so ecstatic that you got up and blessed me, joining in the hymn.... Tell me, however, do you ever sing  I dont mean music of the spheres but our mortal songs with musical intervals as we understand, as for instance Mother does?
No  I dont sing on the physical plane. My education in England was badly neglected  though people say to the contrary. I filled in most of the lacunae afterwards, but some remained of which the musical gap is one. But that is no reason why I should not sing on the supraphysical plane where you met me. There is no exact correspondence between the formation here and the formations there. On the contrary on these inner planes the subliminal as they call it in Europe  that is to say, our inner selves  is full of powers which have not emerged  yet at least  in the physical consciousness. And especially as I was full of Shiva in your experience there is no reason why I should not have sung for I suppose Shiva sings as well as dances?
