subtle is cause.
subtle is cause and gross is effect. and by very nature of it as we go deeper and deeper. there is less and less. and with every iteration of understanding depth comes sense of ease and confidence. you just understand the nature of things. a lot of time you are able to leave it, becuase it makes no sense. or you are able to see the stupidity of it. like a man sees a dog going round and round chasing his own tail. there is also a sense of satisfaction arises with what it is.
I believe this is what the yogis and intellactuals did. they went deeper and deeper until they found fundamental cause the conciousness and the play of nature. the trick here is you have to be relaxed in your quest. because at every step you can really grow, or get dilluded to believe that you are growing. it happens when you become greedy. effect is somewhat frustating and opposite. don’t underestimate the power of compoundingly growing everyday.
