O King, once a wasp forced a weaker insect to enter his hive and kept him trapped there. In great fear the weak insect constantly meditated upon his captor, and without giving up his body, he gradually achieved the same state of existence as the wasp. Thus one achieves a state of existence according to one’s constant concentration.
