Lord Krishna is called Padamnabha, his solar plexus was like a fully blossomed flower. Padma not only means lotus, it also means flower. Fully blossomed flower is usually referred to as padma.
Like this, there are 33 rays of Divinity. There is one light, one God, one Parmatma yet there are 33 aspects. Devas are the 33 different aspects of Divinity. Here crores is not referred to as a number. The Divine has no form but ancient saints have said you can adore Him in any form or name. All the thousand names belong to God only. This is very, very deep science or deep knowledge. It’s amazing. When you go deeper into this, then you feel the ‘wow’. People - who have written this, have discovered this - have simply stupendous knowledge. The Universe is not so simple. It’s very complex. Modern physics also say that the deeper and deeper you go, there are so many different type of particles. So the universe is diverse. The Divinity which manages, rules, and has made this diverse universe is devta.The English name, David, is a Sanskrit word. Dev + vid, dev means Divinity, vid means to know. David means one who knows Divinity. Divinity is not somewhere up in the heaven. It is present in the world, universe, everywhere. And it has to be realized when the mind is calm, serene and settled in our heart and when the emotion and intellect merge into a serene blend in silence then you are able to perceive the subtle reality of Universe and that is devta.
