One of the features of yoga, which can be confusing at first, is that a variety of forms of yoga are practiced. Together, they are called yoga. While these share common elements, some focus more on postures and breathing exercises, whereas others have a greater focus on spirituality. Each emphasizes a particular path that comprises a certain set of beliefs, practices, and rituals. Yoga forms constitute a ladder of sorts, from the "lowest" form of Hatha yoga, with its focus on physical postures and breathing techniques, to the "highest" form known as Raja, or "union by mental mastery."

Newer forms of hybrids of yoga are also proposed such as Power yoga or Acu-yoga. There are also variations of yoga depending on "the teacher that is being followed."

Hatha yoga ("the yoga of vitality')

An easy-to-learn basic form of yoga. Very popular in the United States. Hatha Yoga is the foundation of all Yoga systems. Hatha Yoga is the preparation for higher Yogas. Ha means "sun" and tha means "moon." Thus, Hatha Yoga refers to positive (sun) and to negative (moon) currents in the system. These currents are to be balanced and mastered so that vital force, prana, can be regulated, the mind cleared and superconscious states experienced.
