In all, there are three kinds of wisdom:
(1) The wisdom of hearing
(2) The wisdom of reflection
(3) The wisdom of meditation.
Gradual training in these will result in the perfect accomplishment of vipashyana, primordial and nonconceptual wisdom.
This wisdom destroys the defilements that prevent the attainment of liberation and removes the cognitive obscurations that prevent omniscience. It is the unmistaken knowledge, first, of ultimate reality, the profound nature of things, and second, of all phenomena that arise within the sphere of deluded perception.
Equipped with such knowledge, one is able to pass swiftly through the city of existence, which karma and defilements have made so difficult to cross. Thus, one goes beyond suffering and reaches nirvana with ease.
The six transcendent perfections, generosity and so forth, are causally interrelated and are arranged progressively in terms of subtlety and elevation. They are called transcendent because they are all combined with transcendent wisdom. (Kangyur Rinpoche)
