Yoga is an ancient Indian science of body mind and spirit.
Astanga Vinyasa yoga is a powerful dynamic form of yoga where a
specific sequence of body postures, the asanas, are practiced. In
combination with a special breathing technique (Ujaii pranayama), a
system of breathing/movement (vinyasa) is generated. The heat you
produce in the practice purifies [burns, cleans] and strengthens the
whole body. The focus (gaze) on the points of concentration (drishtis),
the constant breathing makes this practice a meditation in motion.

The original System of Astanga Vinyasa Yoga was taught by
Sri K. Pattabhi Jois (1915-2009), called Guruji by his students,

and is taught at the moment by his grandson Sharath in Mysore/india.

Balance and relaxation for body mind and soul
Balancing and relaxing for your fitness and well-being

The word astanga consists of asta: eight, and anga: limb, first in
written form in the Yoga Sutras of Patanjali
(~ 200 B.C. – 200 A.C).
These 195 verses are the basis for all styles of yoga.

The eight limbs of astanga yoga:

Yama :: general ethics/commandments, the attitude we take towards the outside world, conscious action, restraints) how we conduct ourselves towards others
• Niyama :: our inward orientation, mindset, awareness in thoughts,
  personal observance. How we treat ourselves
• Asana :: yogic body postures
• Pranayama :: breath control
• Pratyahara :: retraction of the senses , to withdraw oneself from that which nourishes the senses,
  withdrawal – control of the senses from attachment to external objects
• Dharana :: Fixation of Attention, immovable concentration of the mind. Single focus.
• Dhyana :: meditation, devotion. Absorption.
• Samadhi :: a state of peace, fully integrated consciousness, all-one

As the limbs of the body grow, the limbs of yoga, on the yogic path grow.
Each and every part for itself and in permanent relation/interaction
to each other.
