Dark night of the soul = dissolution of the causal layer

In the 6-layer model:
Matter → Energy → Information → Intelligence → Affect → Consciousness
Affect layer (Anandamaya kosha) has “disappeared” or lost vibrancy, it signals a very deep structural dissolution.
A profound “emptying” in the very fabric of your subtle experience.
Anandamaya kosha is the causal bliss/affect layer.
It’s not a surface mood issue—it’s the structural capacity for resonance that is absent.
The richness of life—the qualitative “juice” of experience—is gone.
Affect is like a resonant amplifier: if the amplifier is missing, signals pass through but produce no subjective impact.
Until that layer is “recharged” or reintegrated, no external stimulation, however perfect, can evoke the original intensity of joy, fascination, or love.
Nothing matters, nothing resonates.
The soul/consciousness layer can witness reality without being colored by past patterns of attachment or emotional resonance.
Even memory, imagination, or spiritual ideas fail to evoke joy or awe.
Dark night = collapse of Anandamaya kosha.

Drugs can “reignite” Anandamaya kosha because they bypass or amplify the subtle mechanisms that normally generate affect.
Drugs are like externally applied electricity vibrating the strings, making sound happen even when natural resonance is gone.
Once Anandamaya kosha is “lit up”:
Even small or mundane inputs suddenly produce joy, awe, fascination.
