Transformation and unclogging
In the past couple of pages, I described the path of tantra in terms of “unclogging.”
Most often, descriptions of tantra center instead on “transformation.” Tantric methods transform “poison into medicine”: negative emotions such as anger into positive mental qualities like clarity. It’s useful to understand that explanation. (If you’d like to learn more, I recommend Ngakpa Chögyam’s Spectrum of Ecstasy.)
“Transformation” is the language of the generation approach to tantra. “Unclogging” is the language of the less well-known completion approach. They can be understood as different descriptions of the same process.
According to the completion approach, it is only possible to “transform” anger into clarity because they are already the same kind of energy. There is only a superficial appearance of change. At a deeper level, clarity is just anger whose channel has been unblocked, so it runs clear. Or, more accurately, anger is only clarity that has been bottled up so it turns stagnant and rotten.
