Revākhaṇḍa ascribed to the Vāyupurāṇa (RKV) 83.51

83.51

anitye putri saṃsāre kanyādānaṃ dadāmy aham /
śvaḥkṛtyam adya kurvīta pūrvāhṇe cāparāhṇikam /
na hi pratīkṣate mṛtyuḥ kṛtaṃ cāsya na cākṛtam //

"In this transient cycle of existence, O daughter, I shall give the gift of a maiden; / one should do today what is to be done tomorrow, and in the forenoon what is of the afternoon; / for Death does not wait [to see] whether a person's work is done or not done."
