Tapas is any practice that pushes the mind against its own limits, and the key ingredient of tapas is endurance. Thus in the archaic Rig-Veda (10.136), the long-haired ascetic or keshin is said to “endure” the world, to “endure” fire, and to “endure” poison.1 The keshin is a type of renouncer, a proto-yogin, who is a “wind-girt” (naked?) companion of the wild God Rudra (Howler). He is said to “ascend” the wind in a God-intoxicated state and to fly through space, looking down upon all things. But the name keshin harbors a deeper meaning, for it also can refer to the Sun whose “long hair” is made up of the countless rays that emanate from the solar orb and reach far into the cosmos and bestow life on Earth. This is again a reminder that the archaic Yoga of the Vedas revolves around the Solar Spirit, who selflessly feeds all beings with his/her/its compassionate warmth. The early name for the yogin is tapasvin, the practitioner of tapas or voluntary self-challenge. The tapasvin lives always at the edge. He deliberately challenges his body and mind, applying formidable will power to whatever practice he vows to undertake. He may choose to stand stock-still under India’s hot sun for hours on end, surrounded by a wall of heat from four fires lit close by. Or he may resolve to sit naked in solitary meditation on a windswept mountain peak in below-zero temperatures. Or he may opt to incessantly chant a divine name, forfeiting sleep for a specified number of days. The possibilities for tapas are endless. Tapas begins with temporarily or permanently denying ourselves a particular desire—having a satisfying cup of coffee, piece of chocolate, or casual sex. Instead of instant gratification, we choose postponement. Then, gradually, postponement can be stepped up to become complete renunciation of a desire. This kind of challenge to our habit patterns causes a certain degree of frustration in us. We begin to “stew in our own juices,” and this generates psychic energy that can be used to power the process of self-transformation. As we become increasingly able to gain control over our impulses, we experience the delight behind creative self-frustration. We see that we are growing and that self-denial need not necessarily be negative. The Bhagavad-Gītā (17.14–16) speaks of three kinds of austerity or tapas: Austerity of body, speech, and mind. Austerity of the body includes purity, rectitude, chastity, nonharming, and making offerings to higher beings, sages, brahmins (the custodians of the spiritual legacy of India), and honored teachers. Austerity of speech encompasses speaking kind, truthful, and beneficial words that give no offense, as well as the regular practice of recitation (svādhyāya) of the sacred lore. Austerity of the mind consists of serenity, gentleness, silence, self-restraint, and pure emotions.
