Various types of material substances form the basis of bodies, speech, mind and respiration of living beings. They are also responsible for sensual pleasure and pain, life and death. The function of worldly souls is to help each other. The function of the sixth entity, time, is to support the existence, modifications and activity of other entities, and high and low priority. The activity of body, speech and mind is called yoga.
Yoga causes the influx of karmic particles towards the soul of an individual.
Living beings affected with passions, gain the influx of durable and mundane karmic particles while others have the influx of transient karmic particles. The difference in the influx of karmic matter is caused by the intensity or mildness of passions, intentional or unintentional nature of the act, the living being and the environment, and the power to do the act. The activities of body, speech and mind of the worldly souls, affected with passions of anger, pride, deceit and possessiveness, are the root cause of the influx of karmic particles. It makes little difference whether the individual performs the act himself, gets others to do the act or persuades others to perform the act. Neglect of the principles propagated by the omniscient, of the scriptures, of religion and religious personages causes the influx of perception-deluding karma.
