Anandamaya kosha (the bliss body) is the transcendental dimension of human personality existing in total absence of pleasure or pain. 'Ananda' has is a particular state where where there is awareness of neither pain nor pleasure. At that time, a total homogeneity is experienced, and this state of homogeneous awareness is known as anandamaya. Normally, when pain or pleasure is experienced, the the brain produces mental fluctuations. However, in anandamaya kosha, there is no experience. The instrument of experience of pain and pleasure has been totally transcended.
