આસન મારે કયા હુવા, મારી ન મનકી આશ;

āsana mārē kayā huvā, mārī na manakī āśa;

Literally: What is the use of sitting in a meditative posture if you have not killed the desires of the mind?
What it means: Physical discipline and outward religious practices are meaningless without inner mental control.
