Yoga -- ashtanga and hatha yoga.
Through asana (physical postures) and pranayama (breath regulation) students/practitioners engage with yoga to create health and balance in body and mind. These preliminary steps of posture and breath, while healthful in and of themselves, prepare practitioners for the deeper aspect of yoga -- meditation.
Yoga asana practice improves joint and vertebral/spinal health. It helps free stuck energy and brings balance to our energy system increasing overall health of body and mind. Benefits also include increased muscular strength, freedom and flexibility in movement, reduced stress, and greater body awareness.
Taught in the correct manner it is approachable for all, and good teaching should be flexible and tailored to each student’s needs. Yoga is for everyone. The benefits of practicing yoga can change your life for the better.
Tantra yoga -- kriya and kundalini yoga practice focuses on the human energy system/channels of the body (nadis) via breath. Through experience of the chakras (nerve plexuses) through hot/cold breathing the practitioner taps into the level of the emotions and the mind via the nervous system, and with proper practice one can achieve balance therein.
