Om Sathguru Sri Seshadri Swamigal Thiruvadikkae
Is God is therefore both one and many at the same time?
Yes, depending on your vantage point. You can see Him as the one, or you can experience Him as the many.
If you look at the sun from the point of view that it is one, you will see it as one. But if you look at the sun’s individual rays, you will see that they are endless. The same is true in relation to God and His Creation.
