In Hinduism karma is always treated as accountant general of cosmic system that keeps track of every single action indulged by living beings including human beings be they physical or in thoughts. As per doctrine of Bhava karma in Jainism every single thought precipitates into an act of karma. No human being can ever say I am idling for in that idling also karma is envisaged.
The deeper we go into Hinduism primarily teachings of Lord Krishna in Bhagavad Gita, we realize that roots of real karma laid in nishkama karma yoga. It is nishkama karma yoga that is expected of seekers, something that never creates any bondage. All spiritualists, spiritual travelers must indulge in karma in a way that it does not create residual bondage any further.
As a seeker we have to stop the flow of thoughts to our brain in totality. If earthly bondages keep multiplying, how shall we plug the flow of karma in our life! Nishkama karma yoga simply means indulgence in karma with an unattached attitude (never detached). If we are not attached to fruits of karma indulged by us, we never create any bondage.
JRD Tata, a pioneer Karma Yogi all his life indulged in karma nishkama karma way of life. Although teachings of Bhagavad Gita were never part of JRD’s daily routines, he inherently followed teachings of Bhagavad Gita every second of life. For JRD welfare of mankind, his workers and his clients was above all. He always indulged in day-to-day routines of life with an unattached attitude as if everything all the time belonged to God Almighty.
JRD Tata bluntly said that he was not the owner of Tata Empire but only a caretaker, a trustee in whose hands God Almighty trusted the Tata Empire. Human beings like JRD are difficult to find. I deeply respect Ratan Tata but not to the extent I believed in JRD Tata. Behind the entire technological development of India lay the monumental support of JRD Tata.
Who can explain the definition of karma better than JRD himself who never for a moment in his lifetime indulged in bad karma! If there is anyone who equalizes him is King Janaka (father of Sita in Ramayana) who also indulged in affairs of this country with an unattached attitude. King Janaka also was a Karma Yogi par excellence.
If we can indulge in biographies of JRD Tata and King Janaka, we shall truly realize the meaning of karma in Hinduism.
