The author of Kuntros Hasfaikos cited the thought that even if a person was able to see the most amazing and fantastic sights of the universe and understand all the universe’s spiritual secrets, he would not have full pleasure until he was able to relate to his friend what he has seen. In a similar vein, every wise man has a desire to share his ideas and thoughts with others.
Rabbi Chaiyim Shmielevitz commented that this is not a fault, but a virtue. A person does not feel complete pleasure if he does things solely for and by himself. Your own pleasure is enhanced when you share with others. ~ R’ Zelig Pliskin
