[Advaita-l] Whether darkness is bhava - Vivarana Prameya Samgraha of Shri Vidyaranya

[Venkatesh Murthy]

Namaste

I also was saying the same thing. NAND of 5 lights. Darkness =
NAND(Light1,Light2,Light3,Light4,Light5). When even 1 light is switched off
the NAND value is 1. Darkness is present. All lights should be switched on
to make NAND value 0.
