Aspect is a term used across several religions and in theology to describe a particular manifestation or conception of a deity or other divine being. Depending the religion, these might to disjoint or overlapping parts, or methods of perceiving or conceptualizing the deity in a particular context.
In the Bahá'í Faith, this might be conceived as a Manifestation of God.
In Christianity, the concept of the Trinity views God as 3 distinct parts, whereas Sabellianism conceives of one deity manifested in three separate aspects or modes.
In some conceptions of Hinduism, Vishnu is seen as aspect of Brahman.
In Sikhism, there are three distinct aspects: God as deity; God in relation to creation; and God in relation to man.
