cycle of Birth and rebirth,

Hare Krishna
It is association of time, tendencies, fate, chance, Past deeds, with the soul that is cause of the body, Soul alone is not regarded as the cause, Seen alone cannot be the cause of sprout, nor the earth, nor the farmer, it is combine truth that makes it to sprout, Soul gets mixed up with these items through themselves and falls pray to the cycle of Birth and rebirth,
                                               Jai Sri Krishna
