Nigredo (Blackening)

Nigredo, or blackness, in alchemy means putrefaction or decomposition. The alchemists believed that as a first step in the pathway to the philosopher’s stone all alchemical ingredients had to be cleansed and cooked extensively to a uniform black matter. In analytical/Jungian psychology, the term became a metaphor "for the dark night of the soul, when an individual confronts the shadow within".

Lyrics
The song contains a sample of the traditional Indian religious piece "Aarti Shri Ramayan Ji Ki", in particular the line tat maat dab vidhi tulsi ki, aarti shri Ramayan ji ki (तात मात सब विधि तुलसी की, आरती श्री रामायण जी की).
