Self-Inquiry is merely to ‘quiet the mind’.
It’s a fast method to ‘quiet the mind’.
For when you ask,
«To whom does this come?
It comes to me», and you hold on to that me by inquiring,
«‘Who am I?’
What is ‘I’?»
And saying ‘I-I’ to yourself,
‘I-I’, the mind becomes quieter and quieter.
The deeper you go within yourself the quieter you become.
And that’s your sadhana.
That’s all you have to do.
