"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.
One who can fix his mind on Kṛṣṇa without deviation attains śānta-rasa, the steadfast position in Kṛṣṇa consciousness. One in śānta-rasa exhibits two main qualities: unflinching faith in Kṛṣṇa, and the cessation of all material desires. These specific characteristics of śānta-rasa—unflinching faith in Kṛṣṇa and cessation of all desires not connected with Kṛṣṇa—are common to all other rasas as well, just as sound is present not only in sky, where it is produced, but also in all the other elements—air, fire, water and earth. So these two characteristics of śānta-rasa are also present in dāsya-rasa (servitorship), sakhya-rasa (fraternity), vātsalya-rasa (parental affection) and madhura-rasa (conjugal love).
