Om in the context of "Religious image"

A religious symbol is an iconic representation intended to represent a specific religion, or a specific concept within a given religion.

Religious symbols have been used in the military in many countries, such as the United States military chaplain symbols. Similarly, the United States Department of Veterans Affairs emblems for headstones and markers recognize 57 symbols (including a number of symbols expressing non-religiosity).

In the Vedic and Hindu religions, Brahman (Sanskrit: ब्रह्मन्; IAST: Brahman) has a "variety of meanings," but in the Upanishads and later Indian philosophies it connotes 'That' from which all existence proceeds, and to which everything returns, the origin and cause of all that exists. In contemporary Hindu metaphysics it is the highest universal principle, the Ultimate reality of the universe.

Brahman is a concept found in the Vedas, and it is extensively discussed in the early Upanishads, with a variety of meanings. According to Gavin Flood, the concept of Brahman evolved and expanded from the power of sound, words, and rituals in Vedic times to the "deeper foundation of all phenomena," the "essence of the self (Atman, Self)," and the deeper "truth of a person beyond apparent difference." Other scholars such as Barbara Holdrege, Hananya Goodman, and Jan Gonda, contend that the earliest Vedic verses suggest that this ancient meaning was never the only meaning, and the concept evolved and expanded in ancient India.

A mantra (/ˈmæntrə, ˈmʌn-/ MAN-trə, MUN-; Pali: mantra) or mantram (Devanagari: मन्त्रम्) is a sacred utterance, a numinous sound, a syllable, word or phonemes, or group of words (most often in an Indo-Iranian language like Sanskrit or Avestan) believed by practitioners to have religious, magical or spiritual powers. Some mantras have a syntactic structure and a literal meaning, while others do not.

ꣽ, ॐ (Aum, Om) serves as an important mantra in various Indian religions. Specifically, it is an example of a seed syllable mantra (bijamantra). It is believed to be the first sound in Hinduism and as the sonic essence of the absolute divine reality. Longer mantras are phrases with several syllables, names and words. These phrases may have spiritual interpretations such as a name of a deity, a longing for truth, reality, light, immortality, peace, love, knowledge, and action. Examples of longer mantras include the Gayatri Mantra, the Hare Krishna mantra, Om Namah Shivaya, the Mani mantra, the Mantra of Light, the Namokar Mantra, and the Mūl Mantar. Mantras without any actual linguistic meaning are still considered to be musically uplifting and spiritually meaningful.

Para Brahman or Param Brahman (Sanskrit: परब्रह्म, romanized: parabrahma) in Hindu philosophy is the "Supreme Brahman" that is beyond all descriptions and conceptualisations. It is described as beyond the form or the formlessness (in the sense that it is devoid of Maya) that eternally pervades everything, everywhere in the universe and whatever is beyond.

"Parabrahman" is a term from Indian philosophy and spiritual practice that refers to the supreme divine being or absolute reality possessing boundless wisdom, infinite love and universal power. In various teachings and traditions it may be identified with the Supreme God, Nirguna Brahman (the impersonal Absolute) or other aspects of Universal Consciousness.

Over the millennia of its development, Hinduism has adopted several iconic symbols, forming part of Hindu iconography, that are imbued with spiritual meaning based on either the scriptures or cultural traditions. The exact significance accorded to any of the icons varies with region, period and denomination of the followers. Over time some of the symbols, for instance the Swastika has come to have wider association while others like Om are recognized as unique representations of Hinduism. Other aspects of Hindu iconography are covered by the terms murti, for icons and mudra for gestures and positions of the hands and body.

The Trimurti is the triple deity of supreme divinity in Hinduism, in which the cosmic functions of creation, preservation, and destruction are personified as a triad of deities. Typically, the designations are that of Brahma the creator, Vishnu the preserver, and Shiva the destroyer.

The Om symbol of Hinduism is considered to have an allusion to Trimurti, where the A, U, and M phonemes of the word are considered to indicate creation, preservation and destruction, adding up to represent Brahman. The Tridevi is the trinity of goddess consorts for the Trimurti.
