Inauspicious psychic colour - The inauspicious flow of Bhāva (1) (disposition at subtle level of consciousness);
the Kṛṣṇa (black psychic colour), Nīla (blue psychic colour), and Kāpota (grey psychic colour) - these three are Adhartnaleśyās, on account of which the Jīva (soul) mostly attains Durgati - (deteriorated reincarnation).
kiṇhā nīlā kāū, tinni vi eyāo ahammalesāo. eyāhi tihi vi jīvo, duggaiṃ uvavajjaī bahuso...
