Manava Dharmashastra 4.42

4.42

vṛddhivacanaṃ stutireva |

Of that same man, if he avoids the woman covered with impurity, intelligence, vitality, strength, sight and longevity flourish.—(42)

Medhātithi’s commentary (manubhāṣya):
This mention of flourishing also is purely commendatory.—(42)

This verse is quoted in Vīramitrodaya (Āhnika, p. 562), which explains it to mean that if the man avoids her during the first four days, his wisdom and other things become enhanced;—and in Hemādri (Kāla, p. 726).
