You want to initiate and cause to self-perpetuate an involutionary process of spontaneous Self-recognition of buddha-qualities.
If the dharmakaya is a mirror, then its reflections must arise as obvious goodness. If the mind is a brain, then the introduction of subjective hyperlucidity at the synaptic level must induce a physiological response correlating to ecstasy. If the brain is a king, then each of its subjects must submit to its divine law. If the king as a thing is a tyrant, then each of its victims must discover the secret power that connects them to the king. If the king as a thing is beloved, then each of its members is overwhelmed with gratitude. Prehend this as dharmakaya.
Neurologically, the notion of “bodhisattva engagement with the other realms” must signal to the brains of sincere meditators that the anticipated process of catastrophe is real and absolutely must be overcome via the will to maximum consolidation of the self-sense. Socialisation among humans must take on a much more ecstatic evolutionary flavour to compensate for the increased somatic discomfort associated with a compromised sense of agency.
