2.7.22

pāruṣyaṃ rabhasatvaṃ ca pauruṣaṃ teja ucyate/
aśaktir ārtirvyāvṛttir abalatvaṃ ca yoṣitaḥ//

"The characteristics of manhood are said to consist of roughness and impetuosity, while weakness, tenderness, sensibility, and an inclination to turn away from unpleasant things are the distinguishing marks of womanhood. The excitement of passion, and peculiarities of habit may sometimes cause contrary results to appear, but these do not last long, and in the end the natural state is resumed."
