Buddhist-Meditation-Systematic-and-Practical

iii. Vajrayana
Defilements—both jneya and klesa—are of two kinds,
acquired (already destroyed in Mahayana meditations)
and innate, and the latter are very hard to meditate away.
While the former are psychical, the latter pertain to the
body, and it is very difficult to still the subtle
movements they cause in the mind with their ultra-fine
energies. By the Mahayana teachings it will indeed take
a long time to do this; it is possible however, by the
methods of practice given in the Third Initiation of
Anuttarayoga, to rid oneself completely of these very
subtle obstacles. This is done by the discovery of the
innate wisdom, only possible in the Vajrayana.
