Happiness

The atman which is in knowledge unites with the atman which is in the mind. But apart from this, a part of the atman is in happiness. The atman which is in happiness merges with the atman which is in knowledge. The atman which is in happiness also has the form of a bird. Happiness from seeing objects of desire is the head, happiness from obtaining objects of desire is the right wing, happiness from savouring objects of desire is the left wing, and ordinary happiness is the centre of the body. Happiness from uniting with the brahman is the tail. There is a Shloka about this.
