The Atman might be mortal.
The body of the Teacher, is mortal.
The Truth might be timeless, but the Teacher, as a body, has only definite time.
He uses that time.
And that is the only proper use of anybody’s time – to move into the timeless.
That is the proper use of life, in this dualistic world – to move into that, which is beyond duality.
So, the Guru, the Teacher, spends his life, spends his time, holding the hands of others, ushering them, escorting them, into the timeless.
That is the use of his time.
