Hindu Cosmogony

When the term cosmogony is used the planets, stars, galaxies, black holes etc is usually what comes to mind, but in the Yoga sense I prefer to put it differently.

Yoga theory states that the world is essentially the creation of the Mind, i.e God's mind, that the very concept of material reality, physicality, is a creation of the Mind and hence reality itself begins with the mind. Note that although this bears some similarity with quantum reality, which some Buddhist thinkers have developed a great interest in, it is different in the sense that the quantum reality itself is considered to be projection of the mind.

Western science deals with the world as purely something out there existing in its own right. The Yoga viewpoint is that reality begins with the observer, not the objects perceived. If you are going to study the world, the mind of the scientist is the first thing to observe, because the whole concept of the world, a world, starts with the sense and thought processes of the scientist, the observer, and it is only from the basis that reality itself may be understood. So in effect the vast universe is the creation of God's Mind, in effect is IN God's Mind a well as being a reflection, a product of God's mind. It is through unity of beings with God's being that we can really see the universe as it is.

Thus only by a deep level of internal self-reflection can the world be understood. Not knowing much about Yoga processes myself I have to state that what could be a fact for the Yogin is likely to be described to a Westerner as a belief.

If there is flaw in the Western outlook it is its insistence that what may be a hard reality for other cultures is a belief.
If the non gnostic nature of Western religion, namely the nature of Christianity makes belief the basis of the religion, it is wrong to project that concept onto other religions.
