The word śama means controlling the mind and keeping it from being diverted in various ways by fixing it on the Supreme Personality of Godhead. When one's mind is fixed on the Supreme Lord, he is known to be situated on the śama platform. On that platform the devotee understands that Kṛṣṇa is the basic principle behind everything that is within one's experience. This is also explained in Bhagavad-gītā (BG 7.19). Such a person can understand that Kṛṣṇa is present in everything and is distributed all over the cosmic manifestation. Although everything is under the control of the Supreme Lord and is situated in His energy, everything is nonetheless different from Kṛṣṇa in His personal form. It is also stated in Bhakti-rasāmṛta-sindhu that one who understands this, whose intelligence is fixed on Kṛṣṇa, has attained the platform of śama. Moreover, the Supreme Personality of Godhead says: śamo manniṣṭhatā buddheḥ: Unless one is elevated to the platform of śānta-rati, he cannot be fixed in knowledge of the greatness of Kṛṣṇa or of the diffusion of His different energies, which are the cause of all manifestations. This same point is explained in Śrīmad-Bhāgavatam (SB 11.19.36):
- śamo manniṣṭhatā buddher
- dama indriya-saṁyamaḥ
- titikṣā duḥkha-sammarṣo
- jihvopastha jayo dhrtiḥ
Stability of mind can be 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 śama. When one is ready to tolerate all kinds of sufferings in order 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 dhṛtiḥ. From dhṛtiḥ, one becomes dhīra, pacified. A pacified person is never disturbed by the urges of the tongue and the genitals.
