A type of Śalya (a weapon in the interior which is rankling inside);
that negative Bhāva (1) (disposition at subtle level of consciousness) which acts as an emotional weapon (rankling inside); such Bhāva rises in the form of Nidāna (longing for material prosperity as the reward of penance) and impedes the practice of Saṃyama (self-restraint or ascetic conduct).
