Karma Yoga – the simple yoga which yields the fruits that no other yoga can give.
Krishna while giving knowledge on the war-front referred Karma Yoga as the best yoga of all to Arjuna. In his preaching to Arjuna, Krishna says, an individual can achieve liberation or the Supreme Being (God) just by performing karam defined for him in scriptures. An individual based on his caste is expected to perform karma. In ancient time, there were discrimination of karma for Bhramin, Shudra and Vaishya. There is no such discrimination today as one can see Bhramin indulged in act of corruption and vaishya imparting knowledge of scriptures. Though people are not having complete knowledge on the topic they preach others. If we take base of Gita, I believe instead of preaching one can present views if his knowledge is sufficient otherwise refrain from making any speech.
According to Krishna, karma done whole-heartedly with selflessness and any expectation of reward is the best of all can be done by an individual. One should not be attached with the act done by him. Any feelings like pain, happiness, pride… can take away the fruits of karma.
Some people count the number of deeds done with selflessness, devotion…Supreme Being never counts such deeds. Knowledge of karma is good to have, but the best learned is the performer, who does all act as if he is doing act for the wellbeing of other lives with the thought, he is performer not the creator.
I hear people commenting on number of hours they spend on Yoga and Meditation. And all the time I wonder how can we measure Yoga and Meditation? I know such people will not be able to give justification on this question as they hardly understand the importance of Yoga and Meditation.
Keeping all this aside, the truth of the universe is, “Karma done hole-heartedly, with selflessness, dedication and as a performer, that is without any attachment”.
