This same point is explained in Śrīmad-Bhāgavatam (11.19.36):
- śamo man-niṣṭhatā buddher dama indriya-saṁyamaḥ
- titikṣā duḥkha-sammarṣo jihvopastha-jayo dhṛtiḥ
"Śama, equilibrium of mind, is achieved by one who has concluded that the Supreme Personality of Godhead is the original source of everything. And when one can control his senses, that is called dama. When one is ready to tolerate all kinds of sufferings to control the senses and keep the mind steady, that is called titikṣā, or tolerance. And when one can control the urges of the tongue and genitals, that is called dhṛti." One who has attained dhṛti is a dhīra, a pacified person. A pacified person is never disturbed by the urges of the tongue and genitals.
