The Bodhisattva's Nirvana is perfect tranquillization, but it is not extinction nor inertness; while there is an entire absence of discrimination and purpose, there is the freedom and spontaneity of potentiality that has come with the attainment and patient acceptance of the truths of egolessness and imagelessness. Here is perfect solitude, undisturbed by any gradation or continuous succession, but radiant with the potency and freedom of its self-nature which is the self-nature of Noble Wisdom, blissfully peaceful with the serenity of Perfect Love.

(The Lankavatara Sutra)
