4.29.62

mamaite manasā yad yad asāv aham iti bruvan /
gṛhṇīyāt tat pumān rāddhaṃ karma yena punar bhavaḥ //

62. Whatever body the Jīva assumes by virtue of the thought "I am such and such" and "these are mine" he carries with him the Karma wrought with that body which he has been contemplating; for, every successive birth is determined by the memory of the previous Karma.
