Experience of Karma Yoga
In Karma yoga, when you are working for Krishna, you can do your office tasks, speak to people on business, and do whatever you duty happens to be, for it all becomes part of your single aim: to return to God.
Kardama Muni, A First-Class Yogi
Kardama Muni practiced meditative penances on the bank of the Sarasvati River for a period of 10,000 years. It is understood that the yoga system, in order to be rightly practiced, must be performed by persons who possess a very long duration of life.
