Yes. Life cannot be sustained in such a world. Without even black and white, there would be nothing to see. That is why Paticca Samuppada creates a ‘colorful world’ for those who crave such a world. The world is created by ‘mental energy’ (same as kammic energy). The only way mental energy can make a ‘colorful world’ is by saññā built into our ‘mental bodies’ or ‘manomaya kaya.’ Mental energy cannot make ‘colored objects’; only ‘colorless suddhāṭṭhaka’ can be created by kammic energy. It can only generate a saññā (perception) of color. That holds for other entities of taste, smell, etc.
So, only way mental energy can make colorful world is through sanna only and not in real!? Hmm.
A living Arahant can see just like anyone else, because they are also born with the ‘distorted saññā.‘ The difference between an Arahant and a puthujjana is in the cetasika generated. Arahant‘s mind would not generate immoral cetasika (raga, dosa, moha) in response to any sensory event. They only experience the sensory inputs without attaching to them: “‘Diṭṭhe Diṭṭhamattaṁ Bhavissati’ – Connection to Saññā .” Even though an Arahant would still generate (pure, undefiled) citta, they have already attained Nibbana, which is defined as “rāgakkhayo dosakkhayo mohakkhayo—idaṁ vuccati nibbānan” ti OR “the ending of rāga, ending of anger/hate, and ending of ignorance/delusion is Nibbāna.” See, for example, “Nibbānapañhā Sutta (SN 38.1).” Until the death of the physical body (which is a vipaka), an Arahant would experience the ‘colorful world’ just as anyone else.
So, does arahat exhaust all his karma at death i.e. at parinibbana?
The more I understand these things, the more I realize how difficult it is to glimpse nibbana.
