Answer: When we invest our forces in working with the public, we want to succeed for egoistic reasons. Therefore it’s easy for us to continue this work. We invest so much in these people that we already feel them as if they are relatives and we want their success. Therefore dissemination expands our vessels. If we are “cooked” only within the group, ultimately it will degenerate and remain in a static state. We will find it more and more difficult to take steps toward one another and to come closer to each other. This is really what happens.
But if we take care of people, we begin to be concerned for their advancement and success. It’s reasonable that we will advance together with our students, even though each one of them advances according to his level. And when you come from your students to friends, then you already relate to them differently, not like before.
It’s very difficult to reach an immediate and strong connection directly with people who are on the same level with you so as to be like one man with one heart. But only after you are concerned about the people who are on a lower level than you, do you soften and get the feeling of bestowal within your desire to receive, and as a result of this, you will pass to that inclination a desire to bestow toward the friends.
