The word yoga, from the Sanskrit word yuj means to yoke or bind and is often interpreted as "union" or a method of discipline. A male who practices yoga is called a yogi, a female practitioner, a yogini.

The Indian sage Patanjali is believed to have collated the practice of yoga into the Yoga Sutra an estimated 2,000 years ago. The Sutra is a collection of 195 statements that serves as a philosophical guidebook for most of the yoga that is practiced today. It also outlines eight limbs of yoga: the yamas (restraints), niyamas (observances), asana (postures), pranayama (breathing), pratyahara (withdrawal of senses), dharana (concentration), dhyani (meditation), and samadhi (absorption). As we explore these eight limbs, we begin by refining our behavior in the outer world, and then we focus inwardly until we reach samadhi (liberation, enlightenment).

Today most people practicing yoga are engaged in the third limb, asana, which is a program of physical postures designed to purify the body and provide the physical strength and stamina required for long periods of meditation.

Yoga is not a religion. It is a philosophy that began in India an estimated 5,000 years ago. The father of classical ashtanga yoga (the eight-limbed path, not to be confused with Sri K. Pattabhi Jois' Ashtanga yoga) is said to be Patanjali, who wrote the Yoga Sutra. These scriptures provide a framework for spiritual growth and mastery over the physical and mental body. Yoga sometimes interweaves other philosophies such as Hinduism or Buddhism, but it is not necessary to study those paths in order to practice or study yoga.

It is also not necessary to surrender your own religious beliefs to practice yoga.

All you really need to begin practicing yoga is your body, your mind, and a bit of curiosity. But it is also helpful to have a pair of sweat pants, leggings, or shorts, and a t-shirt that's not too baggy. No special footgear is required because you will be barefoot. It's nice to bring a towel to class with you. As your practice develops you might want to buy your own yoga mat, but most studios will have mats and other props available for you.
