The Vajrayana also has its special precepts, among
which is the resolve to develop the bodhicitta so as to
gain full enlightenment in this life (see Ch. XIII, Part

sambodhi and then ultimately save all beings. The
Tantras sometimes criticize exoteric Buddhism, for they
say that the bodhisattvas of the lower stages have no
real power to save others; they just help others to enter
the Buddha's gate.
