Premanand Maharaj Ji

Why is patience and tolerance called the greatest quality?

Tolerance is the heart of saintliness

Bhagwan Kapil Dev named tolerance (titiksha) as a sadhu's first quality, and all of saintliness is found in it.

Bhagwan Kapil Dev named forbearance as the foremost quality of a sadhu (saintly person). Being tolerant holds all of saintliness within it.
