When there is no more mental pain or grief, Nirvana becomes perceptible, comprehensible, inviting and attractive. It is the complete and final cessation of greed and craving, hatred and ignorance and, therefore, the cessation of rebirth and of the continuity of life. Then, the Dharmakaya, Prajna and, consequently, Freedom manifest themselves to their fullest. Nirvana cannot be expressed through words; it has to be experienced.
