“Another dimension of Krishna’s use of the word “field” is brought out by a traditional Hindu anecdote. A wandering Sadhu or holy man is asked what his work in life is; he replies, “I’m a farmer.” When the questioner looks surprised he adds, “This body of mine is my field. I sow good thoughts, and actions, and in my body I reap the results.” The Buddha explains, “All that we are is the result of what we have thought: it is founded on our thoughts; it is made of our thoughts.” What we think, we become, for as Emerson says, the ancestor of every action is a thought. Thus our thoughts, taken together, bear fruit in the actions, decisions, and desires that shape our lives. In part, the body bears the fruit of what we think insofar as our way of thinking affects our health and safety. But in a larger sense, the whole field of human activity (indeed the whole of prakriti (the underlying, “stuff” of existence) is also a “field of karma” – where for example, the global environment is shaped by the sum of what its inhabitants do, which in turn is shaped by how they think.”

~Eknath Easwaran in his translation of the Bhagavad Gita
