Kathok Rigzin Chenpo Rinpoche
The body’s energy can be called “bindu” (tib, tigle). There are gross, subtle, pure and impure forms. It pervades the ovum, blood and all the channels (of the subtle energetic body). Finally, it culminates in the thought-free meditation. All these are referred to as “bindu”. From external to internal, it gets more and more subtle and finally becomes meditation, it can also be called “consciousness”.
How do humans come into being? How does karma arise? From the Vajrayana perspective, karma arises from the pranas (winds) and bindu. The grosser form of bindu can be said to be a soul. In a subtler form, the bindu is our consciousness. In an even subtler form, it is the mind of our fundamental basis, the original mind. That is to say, the basic wisdom awareness (vidya) gave rise to humans. Therefore when all these are purified, one attains the fruition of Dharmakaya. If we were to relate these to the Three Jewels and Three Kayas—the purified channels (nadi) are the Sangha or Nirmanakaya; the purified winds (prana) are the Dharma or Sambhogakaya; the purified drops (bindu) are the Buddha or Dharmakaya.
