Although there are many styles of yoga, the differences are usually about emphasis, such as focusing on strict alignment of the body, coordination of breath and movement, holding the postures, or the flow from one posture to another. All of the styles share a common lineage. In fact, the founders of three major styles - Astanga, Iyengar and Viniyoga -- were all students of Krishnamacharya, a famous teacher at the Yoga Institute at the Mysore Palace in India. Two other styles, Integral and Sivananda, were created by disciples of the famous guru Sivananda. No style is better than another; it's simply a matter of personal preference. More important than any style is the student-teacher relationship.
