Circumstances don’t matter. Only state of being matters.
That is to say: after meeting the nutritional, medical, social, and educational needs of a human, they don’t get happier by doubling or tripling material comfort.
The way to fill that “hole” is to identify the potential we have inside of us. Ask what you really want to accomplish in life? What do you want you existence to have meant? What would you regret to have spent your time on (think of your parents)? And what wouldn’t you regret?
Your meditative practice, and the consciousness it creates, is a genuine contribution to a better, more sustainable and peaceful world.
