The Power of Transformation

Considering that it is not possible to reach Awakening by retaining the impure components of our personality, the Vajrayana proposes a system that allows us to transform impure into pure.

The body becomes the pure body of the yidam, inseparable manifestation and emptiness
Speech becomes the mantra, the pure word, inseparable sound and emptiness
The mind becomes the five wisdoms, pure mind, inseparable intelligence and emptiness

All phenomena are production of the mind. This is why, if one develops sufficient mastery of the mind, phenomena can all be transformed. The Vajrayana uses this power of transformation to undertake the passage from impure to pure.
