one translation I found (there can be many, as many as there are names of the nameless and forms of the formless, naturally, quite):

Om Thou art that, Thou art Narayana, God in the form of man;

Thou art the Embodiment of perfection and the perfect master. Thou art enlightened Buddha; Thou art Subramanya and Ganesha, the remover of obstacles; Thou art the Sun-fire

Thou art Brahma, the Creator; Mazda, the Great One; Thou art Jehovah and the Divine Mother, the creative Energy. O Lord! Thou art the Father of Jesus.

Thou art Rudhra, the Transformer, and Vishnu, the Preserver; Thou art Rama and Krishna; Thou art Rahim, all kindness, always giving and expanding; Thou art the Tao.

Thou art Vasudeva, the Sustenance of all, omnipotent and omnipresent; Thou art Hari, Destroyer of illusion, the blissful Spirit.

Thou art unparallelled, beyond time and fearless of adversities; Thou art Shiva, Creator of the lingam, Symbol of the formless Absolute.
