Tapas — Spiritual Heat and Discipline
Tapas (spiritual discipline, austerity, heat) is the sustained application of will and effort that purifies the practitioner, burns away impurities, and generates the inner heat that catalyzes spiritual transformation.
Tapas (Sanskrit: 'heat') is the ancient concept of spiritual discipline through which the practitioner generates inner heat that purifies and transforms. In Tantra, tapas takes multiple forms: physical austerities (fasting, exposure to heat and cold, sleep reduction), pranayama (the internal heat generated through breath retention), Hatha Yoga practices (particularly tummo and bandhas), and above all the sustained practice of meditation against the resistance of the wandering mind. The Tantric understanding of tapas is more sophisticated than simple asceticism: it is not the punishment of the body but the deliberate generation of the inner fire (Agni/Tapas) that burns away the Malas (impurities) and purifies the Srotas (channels). The Yoga Sutras include Tapas as one of the three niyamas of Kriya Yoga, specifically for purifying body and senses. Ayurveda's science of Agni (digestive/transformative fire) and the Tantric science of Tapas both recognize that controlled heat production is fundamental to biological and spiritual purification.
Tapas is the fire that burns away all impurity. Without it, no practice can reach its destination.
Patanjali lists tapas among the niyamas and, in the Kriya Yoga of Sutra 2.1, pairs it with self-study and surrender; the word literally means 'heat,' the friction of discipline that burns away impurity.

- What Tantra says about habit and discipline
Tapas means heat, and the tantric reading is specific: discipline is not punishment of the body but the deliberate generation of an inner fire that burns off the malas. The Yoga Sutras place it in kriya yoga alongside self-study and surrender — a warning against discipline running on willpower alone.
