From that transcendental subtle vibration arose the oṁkāra composed of three sounds. The oṁkāra has unseen potencies and manifests automatically within a purified heart. It is the representation of the Absolute Truth in all three of His phases — the Supreme Personality, the Supreme Soul and the supreme impersonal truth.

Gauḍīya
Translation
From nāda arose the oṁkāra composed of three sounds and whose origin is unclear. Oṁ is directly the Supreme Lord and causes realization of Bhagavān, Paramātmā and Brahman.
From nāda (tataḥ) appeared oṁ composed of three letters a, o and m, whose birth is indistinct. Oṁ is directly the Supreme Lord (svarāṭ) and is the cause of understanding (liṅgam) Brahman, Paramātmā and Bhagavān. Tat is in the neuter since it is the object of worship for devotees, jṣānīs and yogīs and because it modifies liṅgam.
