Pranayama (Sanskrit: प्राणायाम, "Prāṇāyāma") is the yogic practice of focusing on breath. In yoga, breath is associated with prana, thus, pranayama is a means to elevate the prana-shakti, or life energies. Pranayama is described in Hindu texts such as the Bhagavad Gita and the Yoga Sutras of Patanjali. Later in Hatha yoga texts, it meant the complete suspension of breathing. The pranayama practices in modern yoga as exercise are unlike those of the Hatha yoga tradition.
