 The passions like anger, pride, deceit and greed are called sticky ("kaṣāyas") because they act like glue in making karmic particles stick to the soul resulting in "bandha".The karmic inflow on account of "yoga" driven by passions and emotions cause a long-term inflow of karma prolonging the cycle of reincarnations.On the other hand, the karmic inflows on account of actions that are not driven by passions and emotions have only a transient, short-lived karmic effect.
