12. Experiences of the Inner and the Cosmic Consciousness
A cosmos or universe is always a harmony, otherwise it could not exist, it would fly to pieces. But as there are musical harmonies which are built out of discords partly or even predominantly, so this universe (the material) is disharmonious in its separate 
elements – the individual elements are at discord with each other to a large extent; it is only owing to the sustaining Divine Will behind that the whole is still a harmony to those who look at it with the cosmic vision. But it is a harmony in evolution in progress – that is, all is combined to strive towards a goal which is not yet reached, and the object of our yoga is to hasten the arrival to this goal. When it is reached, there will be a harmony of harmonies substituted for the present harmony built up on discords. This is the explanation of the present appearance of things.
