You bring the thirsty horse to water, and it shakes its head no. You work hard to find your contribution to the world, to help someone in need, to improve a negative situation, or to enjoy your life. What is the point?
Sometimes the point is just to try, to keep trying. We are all but bite size pieces in a cosmic puzzle. We have our part to do and we do it, even when it seems to yield no fruit. What do we know? Is everything that happens perceived by our individual senses? Everything we do has an effect on others so responsibility over our actions is never pointless. Have you noticed how you could easily get stressed out if your boss or client is stressed out, and, conversely, how relaxed you may get when your boss or client acts like he/she trusts you and is pleased with your work? Each individual has an energetic effect over others, positive or negative. Have you ever encountered a time when someone remarks over something you said or did that you don't even remember? Just because you don't remember doesn't mean someone else doesn't remember. We all hang on to different things, a different kaleidoscope of memories we choose, which we call our past, which help form our image of ourselves in the present. This collage of memories could very easily tell an untrue story. I encourage you to take a piece of paper out right now, and write down a list of positive things that happened to you in the past two weeks. If stuck, start the list by writing: "I'm breathing". Then take out another piece of paper and write down a list of all the different things you can think of to try out that interest you. After the 2 lists are done, you can re-create the map of your past and gain perspective about your present and future.
The Bhagavad Gita reminds us that we are all foot soldiers in this field. We are not fighting on behalf of our individual identities, but on behalf of the one Self that permeates the collective - the same energy that ignites the stars and makes planets orbit around the sun. We are all part of something so much bigger than we can see, but we get lost by our own expectations, which are shaped by our limited vision. There are so many exciting possibilities we cannot even imagine yet!
Trusting that we are cared for, we march on.
