Self in the Heart

This is a poetical verison of the eighth stanza of Reality in Forty Verses: Supplement. The circumstances in which it was written are explained in the foiotnote to that stanza

In the inmost core, the Heart
Shines as Brahaman aloner,
As 'I-I', the Self aware.
Enter deep into the Heart
By search for Self, or diving deep, With breath under check.
Thus abide ever in ātman.
