Tapas refers to the inner fire that your practice builds. The principal is to find the level of Tapas or challenge within a practice that is right for you to build this inner fire. If you succeed then you start to cultivate Tejas. Tejas is the radiant, inner glow that someone emotes that draws people to them; a quiet, effortless joy that radiants for no reason save the fact they are alive. Many people want Tejas, that inner glow, in life - however, they have to be willing to do the practice to build it. This flow is all about finding the right challenge to build that inner fire and then resting back into the lightness of your being.
