So there is no cause of becoming sad. Our meeting and separation in the material world is like the flowing tide of the river. During the flowing tide of the river, so many different floating articles meet together, and with the flowing, they again become separated by the movement of the waves. That is the way of the material life. But our separation, although it resembles exactly in the material way, it is completely different. In the spiritual world, separation is more relishable than meeting. In other words, in spiritual life, there is no separation. Separation is eternal, and meeting is also eternal. The separation is simply another feature of meeting.
