Meditation in the Bhagavad Gita is a means to one's spiritual journey, requiring three moral values – "Satya" (truthfulness), "Ahimsa" (non-violence) and "Aparigraha" (non-covetousness). Dhyana in this ancient Hindu text, states Huston Smith, can be about whatever the person wants or finds spiritual, ranging from "the manifestation of divinity in a religious symbol in a human form", or an inspiration in nature such as "a snow-covered mountain, a serene lake in moonlight, or a colorful horizon at sunrise or sunset", or melodic sounds or syllables such as those that "are intoned as mantras and rhythmically repeated" like Om that is audibly or silent contemplated on. The direction of deep meditation, in the text, is towards detaching the mind from sensory distractions and disturbances outside of oneself, submerging it instead on the indwelling spirit and one's soul towards the state of "Samadhi", a state of bliss (Bhagavad Gita, Chapter 6: Yoga of Meditation).
