Yoga, balance between body and mind

Hatha Yoga:
What most people refer to as simply "yoga" is actually Hatha Yoga. Hatha Yoga is a system of yoga introduced by Yogi Swatmarama, a yogic sage in the 15th century in India. This particular system of yoga is the most popular one, and it is from which several other Styles of Yoga originated including Power Yoga, Bikram Yoga, Ashtanga Yoga, and Kundalini Yoga. The word "hatha" comes from the Sanskrit terms "ha" meaning "sun" and "tha" meaning "moon". Thus, Hatha Yoga is known as the branch of Yoga that unites pairs of opposites referring to the positive (sun) and negative (moon) currents in the system.
Hatha Yoga tries to achieve balance between body and mind, as well as attempts to free the more subtle spiritual elements of the mind through physical poses or Asanas, Breathing Techniques or Pranayama, and Meditation.

Power Yoga:
Power Yoga is a system of yoga based around the ancient technique known as Ashtanga Vinyasa. This system uses extreme breath control and constant movement to generate heat. It is with this heat that the body reaches flexibility maximization. The maxim being ' you warm up to stretch.'
This yoga has been used with dramatic results on athletes and sports persons. It uses the body's own weight like conventional weights to build strength coupled with extreme muscle control.
This is a dynamic form which will give balance, strength and incredible flexibility. This is for men and women with a good level of fitness and is suitable for a beginner or an accomplished athlete.

Ashtanga yoga:
Ashtanga yoga is a system of yoga transmitted to the modern world by Sri K. Pattabhi Jois. This method of yoga involves synchronizing the breath with a progressive series of postures—a process producing intense internal heat and a profuse, purifying sweat that detoxifies muscles and organs. The result is improved circulation, a light and strong body, and a calm mind. Ashtanga yoga literally means "eight-limbed yoga," as outlined by the sage Patanjali in the Yoga Sutras.

History of yoga:

Yoga derives from prehistoric roots, and develops out of ancient Indian asceticism.
Yoga as a Hindu philosophy ("darshana") is first expounded in the Yoga Sutras of Patanjali. This earliest school of Yoga retrospectively came to be known by the retronym Raja Yoga to distinguish it from later schools.

Today, many people are taking up yoga techniques for physical exercise, and most don’t know the history of yoga. They believe there is nothing wrong with implementing this form of exercise into their daily regiment to promote a more healthy body. However, the practice of yoga is much more than a system of physical exercise for health. Yoga is an ancient path to spiritual growth, and originates out of India where Induism is practiced.
