Bhagavatapurana 4.29.59

4.29.59

iti veda-vidāṃ vādaḥ śrūyate tatra tatra ha /
karma yat kriyate proktaṃ parokṣaṃ na prakāśate //

59. Thus indeed is frequently heard the view of those who are versed in the Vedas that any Karma laid down by the Vedas when performed ceases to be perceived (as soon as it is finished) and does not appear to be.
