The first phases of tantric sadhana build the alchemical chamber, cleanse, and prepare the flask. The next phase is a series of maneuvers which infuse the ingredients and manipulate the reactions, actuating results. Finally, the work is sealed in the final phases. The alchemical chamber and ingredients have two aspects (1) the container and contained—called realm and beings, (2) the body, speech, and mind as perception and experience.
Preparing the vessel and infusing the ingredients is somewhat akin to the creation of mathematical equations. In general the variables, constants, coefficients, terms, and operators of the equation are arranged to always come up with the same answer—confused ordinary perception. The Tantric alchemist arranges the same items to come up with startlingly different conclusions.
The use of mind’s constructs, languaged perceptions—(both of these communications in symbol as imaged feelings and felt images)—and bio-energies form the workspace of Tantric practice. To these are added the catalyzing ingredients transmitted through empowerments—gnosemic utterance and sensual (visually perceptual) communications of a radically different quality. These catalyzing agents break down not only the rigidity of structures in consciousness, but ultimately the structuring process, so that what lies behind this primal urge can be known directly … And this knowing translated back into the process of appearing now seen and lived in its fullness—not separate from awareness and the mystery beyond awareness.
Each maneuver within the Tantric sadhana fuses body, speech, and mind in new configurations which organically grow, one upon the other, to accomplish the results. It is for this reason that one must understand the content and the context of the transformations happening within a sadhana—how these relate to the lived experience of the practitioner.
The sadhana is not a series of nice ideas or images … it is an equation or recipe for radical spiritual transformation … each word, sentence, verse a symbolic pointer/catalyst/ trigger for an internal change whose cumulative effect is the equations result. - talks on kye rim and dzog rim aspects of Tantric sadhana
