The Guru's silence is more vast and emphatic
than all the sastras put together.
His silence is the highest expression
of the realised non-duality
which is after all the true content of the Vedas.

Though he instructs his disciples,
he does not pose as a teacher,
in the full conviction that the teacher and disciple
are mere conventions born of illusion.

And so he continues to utter words.
