It is enough joy to act as a handicap. The joy is as great as that of a person who has just deposited a huge load he has been long carrying, or as that of a greedy person who has just killed a serpent guarding a vast treasure he wanted to grab. When the sun rises, darkness as well as the troubles arising from it disappear. Similarly, for those who have realised the Atma, there is no longer any bondage, nor the sorrow arising from the bondage. Once egoism enters man, he slips from the ideal and precipitates himself from the top of the stairs in quick falls from step to step, down to the very bottom floor.
Egoism breeds schisms, hatreds and attachments.
Through attachment and affection, and even envy and hatred, one plunges into activity and gets immersed in the world. This leads to embodiment in the physical frame and further egoism.
