Kundalini Yoga is a meditative discipline - or a system of meditative techniques and movements - within the yogic tradition that focuses on psycho-spiritual growth and the body's potential for maturation. The practice of Kundalini Yoga consists of a number bodily postures, expressive movements and utterances, characterological cultivations, breathing patterns, and degrees of concentration.
The movements and the body-work should not - according to some scholars of religion - be considered mere stretching exercises. The concept of life-energy - pranotthana - is central to the practice and understanding of Kundalini Yoga. It also gives special consideration to the role of the spine and the endocrine system in the understanding of yogic awakening. Recently, there has been a growing interest within the medical community to study the physiological effects of meditation, and some of these studies have applied the discipline of Kundalini Yoga to their clinical settings.
