If one can fix his mind on Kṛṣṇa without deviation, he can attain a steadfast position in Kṛṣṇa consciousness, śānta-rasa. When one attains śānta-rasa, unflinching faith in Kṛṣṇa is established, and all material desires cease. These specific characteristics of śānta-rasa—unflinching faith in Kṛṣṇa and cessation of all desires which are not connected with Kṛṣṇa—are common to all other rasas as well, just as sound is generally present in all other elements (air, fire, water and earth) because it is produced from the sky. Similarly, these two characteristics of śānta-rasa are present in other transcendental relationships, such as dāsya (servitorship), sakhya (fraternity), vātsalya (paternal affection), and the madhura-rasa (conjugal love).
