If we combine these two sentences, it turns out that we need to work hard to help a friend get pleasure from making efforts?
Answer: Yes. As a result, the more you work, the more enjoyment you get, not from the results of the labor, but from the work, from the effort itself. When you are correcting egoism, efforts turn into pleasure.
It does not exist in our world. Here we work in order to earn, and earn to buy something or to enjoy something.
Why is the spiritual world infinite and there is no concept of time? Because the very effort includes both effort and its fulfillment, the Kli (vessel). The effort itself is fulfillment.
Start thinking about it, and you will see what a spiritual state is. There is no cause and consequence development of events, so a spiritual state is permanent.
