3. Sri Ramana Maharishi

Yes. It will be so.
 All that is inside will try to come out.

There is no other way except
 to pull up the mind
 each time it wants to go astray
 and to fix it on the Self.

Bhagavan quoted the verse
 in the Bhagavad Gita
 which says
 that as often as the wavering mind
 goes after anything,
 it should be drawn away
 and fixed in the Self.
