karmany arabhate dehi
karmabhis tanute deham
ubhayam tv avivekatah
karmani--material fruitive activities; arabhate--begins; dehi--a
living entity who has accepted a particular type of body; dehena--with
that body; atma-anuvartina--which is received according to his desire and
past activities; karmabhih--by such material activities; tanute--he
expands; deham--another body; ubhayam--both of them; tu--indeed;
avivekatah--due to ignorance.
The living entity, who has received his present body because of his past fruitive activity, may end the results of his actions in this life,but this does not mean that he is liberated from bondage to material bodies. The living entity receives one type of body, and by performing actions with that body he creates another. Thus he transmigrates from one body to another, through repeated birth and death, because of his gross ignorance.
