Sri Sri Ravi Shankar:
Parmatma is the sun, devta is its ray. Without the sun, there is no ray and without the ray, there is no sun. A ray has all seven colors, these all different devtas. God is the combination of all the seven colors. God is certainly not made of one color. When all colors combine, white is obtained and that is Parmatma. You can understand this like different organs - eyes, ears, nose, all combine to form you. Your eyes are different from ears, your nose is different from tongue but all is part of you. The totality of the whole creation, with all the energies is given a name and it is called Parmatma, Parampita (supreme father). In ancient terminology, God is called Parmatma, Parampita.
Why only Parampit , He is also Parammata (Supreme mother).Why should God be called father only? God is also the mother. God is father, mother and God is also the Self. All Gods, goddesses are like rays of the sun, one sunlight and all the rays together is God but these are all different aspects of God. All are different aspects of the one Divine like in one human being, one cell somewhere becomes the eyes, somewhere the ears, somewhere the nose, and all this has happened from one fertilized cell, embryo. So, God is the sum total of all Divine elements and in the Vedic times, ancient rishis identified all these elements and called then devtas. They designated 33 types of Divine energy and called them devta and they tell how these are connected with the cosmos, like the eyes are connected with the sun. They established connection between the micro cosmos and macro cosmos. …It is very amazing analysis, amazing science of unity of the universe. It is not too many Gods, it is aspects of God. Though you are one, you have different functions. When you sleep you are different, when you smile you are different, when you eat, you are different. Crore means category, 33 crores means 33 categories of devas. Crore is also a number, 10 million but here it is not referred to as a number. 33 crore means 330 million and so people started taking that way.
