Vishnu is the name of the Preserver aspect of the triune of Creation, Preservation, and Destruction, personified as Brahma, Vishnu, and Shiva in the Vedic tradition.  In modern worship, Shakti, or Divine Mother, has replaced Brahma the third major branch of henotheistic worship.  Among many personifications are Lakshmi, Vishnu’s wife, and Durga, Shiva’s wife. There are many stories and depictions of Vishnu, and many avatars such as Rama, Krishna, Buddha, and in my view, Christ, Mohammed, Martin Luther, and Bill W. In the henotheistic perspective, he is the Supreme Lord of all, encompassing Shiva and Shakti.

Vishnu’s stride (-kram) is over the Earth, the Sky, and the all-pervading omnipresent essence of the Universe, analogizing to the rising, setting, and absence of the sun.

Surya is the name for one of the most ancient deities in the Hindu tradition, literally meaning ‘the going of the sun’.  In this sense it is the Light aspect of Vishnu.
