When the physical intensity of our activities is slight then we accumulate smaller number of kārmaṇa particles but if the physical intensity is strong then we accumulate large number of kārmaṇa particles to the soul. Kārmaṇa particles have 2 odours, 5 colours, 5 tastes and only four touches (cold, warm, sticky and dry) instead of 8 touches that the physical body has. The soul accumulates the karma in quantity of eight main karmas differ from each other as follows:
Age determining (Āyuṣyakarma) receives the smallest quantity. Body making (Nāma karma) and status determining (Gotrakarma) receive equal quantity but more than S.no. a. Knowledge obscuring (Jñānāvarṇākarma), perception obscuring (Darśanāvarṇākarma) and obstructive (Antarāyakarma) all three receive equal but more quantity than S.no. b, but less than remaining karmas. Deluding (Mohanīyakarma) receive more quantity than S.no. c and less than S.no. e.This is also called a quantity of karmic particles associated with soul due to vibration or activity (yoga). This universe is filled with karmic particles and every self attracts those particles, which are with in its range, like the fire that catches only those inflammable particles which are with in its reach. The quantity of the karmic particles varies according to the passionate activity of the self. If the vibrations are strong more molecules of karmic matter attached to the self, while low vibrations attract less karmic particles. Thus every part of the self attracts karmic particles through the vibrations of yoga and kaṣāya. This process leads to the generation of eight types of karmas.
