The mind is only a bundle of thoughts. The thoughts have their root in the I-thought. Whoever investigates the True "I" enjoys the stillness of bliss.
Ramana MaharshiNobody doubts that he exists, though he may doubt the existence of God. If he finds out the truth about himself and discovers his own source, this is all that is required.
Ramana MaharshiWhen the mind, one-pointed and fully focused, knows the supreme silence in the Heart, this is true learning.
