चित्तवृत्तिनिरोध chitta-vritti-nirodha
The stilling of the mind’s fluctuations.
Yoga Sūtra 1.2, and the literal thesis of the product. It is also a constraint on the interface: this should not become one more fluctuation, so almost nothing here moves.
अभ्यास · वैराग्य abhyāsa · vairāgya
Steady practice, held lightly.
Consistency without grasping. Practice accumulates; it is never a score at risk. A day you miss is noted and nothing more — starting again asks only that you start again.
संध्या sandhyā
The junctures of the day.
Dawn, noon and dusk are when practice has always happened. The rhythm of the day follows them, and so does the light of the interface — evening should read as lamplight, not as a dimmed dashboard.
