Established in being, perform action.
In The Bhagavad Gita, the warrior Arjuna implores Krishna (God disguised as his charioteer) to tell him how to resolve his conflicted impulses over the best course of action.
Arjuna was about to go to war against his cousins and friends. The conflict had long been brewing, and Arjuna's compatriots in the conflict had let many opportunities pass to resolve their issues. Their own reluctance to engage in confrontation had led to more and more aggression from the opposing side. Now, war was imminent.
Because of his great heart, and because he felt love for his enemies, Arjuna hesitated on the battlefield.
Krishna smilingly spoke. "Established in being, perform action."
The process of "being" Krishna points Arjuna toward is meditation itself. When we establish ourselves in being by engaging in the act of meditation, we have freed ourselves to act without the baggage of self protection and manipulation that our previously limited understanding required of us.
When we identify as the ego, we are constantly reacting to others from a place of fear and lack, expecting rejection and protecting the persona the ego has constructed for us.
This is not, in fact, reality. We are not actually this persona. Meditation opens the entirety of nature to us and lets us know that we are so much more.
This is why so many meditators report an experience of feeling lighter, less burdened by the weight of the world, more free to act on instinct.
We become free to perform action.
The Bhagavad Gita is the central excerpt from The Mahābhārata, believed to date back to 400 BCE. It is thought to be the central piece of literature of Hindu philosophy. Mahatma Gandhi used the text to help inspire the Indian independence movement and the principles of non-violence.
