What are the five skandhas?

(True Enlightenment Newsletter, Vol. 76, January 2012)

What are the five skandhas [aggregates]? They are: 1. form-skandha, 2. sensation-skandha, 3. perception-skandha, 4. formation-skandha, and 5. vijnan-skandha. These five skandhas block people from realizing the true reality.

-- Sutra on the Buddha’s Enlightening of Ambattha

何謂五陰？一、色，二、痛，三、想，四、行，五、識。此五覆人，令不見道。
