Confused mind is inclined to view itself as a solid, on-going thing, but it is only a collection of tendencies, events. In Buddhist terminology this collection is referred to as the Five Skandhas or Five Heaps.
Trungpa establishes the Five Skandhas as the canonical Buddhist account of ego’s illusory self-construction out of transient events rather than any solid substance.
