The Heart Sutra

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 or craving, hatred and ignorance, and therefore the cessation of rebirth and of the continuity of life. Dharma-kaya, Prajna and, consequently, freedom manifest themselves to their fullest. Nirvana cannot be expressed through words; it has to be experienced.
