Take the following as truth: Tantrism is also the source of the male and female symbols of the thunderbolt (vajra, also called dorje) and the bell (ghanta), usually present in Buddhist ceremonies, and of the system of lamas or high priests, who are held to be reincarnations of holy men.
Then the following statement: "The study of tantrism leads to a deeper expression of self." is true, false, or inconclusive?
