Wisdom refers to the five wisdoms of the Buddha, self-arisen original wisdom. You should understand what they are, but also that they do not truly exist. If you cling to wisdom as truly existent, you cling to what is not truly existent as truly existent, which is confusion. Rather, think of wisdom and then remember that thoughts of wisdom are self-liberated.

-- Khenpo Tsultrim Gyamtso Rinpoche
