Illness is not cured by saying the word 'medicine,' but by taking medicine. Enlightenment is not achieved by repeating the word 'God' but by directly experiencing God. Talk as much philosophy as you like, worship as many gods as you please, observe as many ceremonies and sing devotional hymns, but liberation will never come, even after a hundred eons, without realizing Oneness, Wholeness.
-Adi Shankara
