Abhinavagupta:
Here, bliss is not like the intoxication of wine or wealth, or even like union with a lover. The emergence of the light of consciousness is not like the light produced by a lamp, by the sun, or by the moon. The happiness of release from accumulated differentiation is a joy like the removal of a burden. The emergence of the light of consciousness is the recovery of a forgotten treasure - the abode of complete non-duality.
