In addition, the word “yoga” often appears in the Bhagavad Gita, a classic Hindu text possibly written as early as the fifth century B.C.{6} In chapter 6, Krishna declares: “Thus joy supreme comes to the Yogi . . . who is one with Brahman, with God.”{7} Finally, in about A.D. 150, the yogi Patanjali systematized yoga into eight distinct “limbs” in his Yoga Sutras. These eight limbs are like a staircase, supposedly leading the yogi from ignorance to enlightenment. In order, the eight limbs are: yama (self-control), niyama (religious observances), asana (postures), pranayama (breathing exercises), pratyahara (sense control), dharana (concentration), dhyana (deep contemplation), and samadhi (enlightenment).{8} It’s interesting to note that postures and breathing exercises, often considered to be the whole of yoga in the West, are steps three and four along Patanjali’s “royal” road to union with Brahman. We see that yoga is an ancient spiritual discipline deeply rooted in the religion of Hinduism. This being so, we may honestly wonder whether it’s really wise for a Christian to be involved in yoga practice. Next, we’ll continue our discussion by examining some of the important doctrinal differences between yoga and Christianity.
