Ans: It’s only logical that there can be only one power that controls everything.  Otherwise it would result in conflicts in the system which is not the case.

Detailed Explanation The presence of some unseen or invisible power behind all the creation is evident. The perfect execution of the system also implies that there is a controller behind the same. If there is more than one controller or creator, we would experience conflicts just as a kingdom would face when it has 2 rulers. Hence there can be only one God who is the controller of the universe. The same is also ascertained in the ve:das, the authoritative scriptures of ours, which mentions de:va ekaha meaning there is only one God. 

Ans: There is only one supreme power. But it’s abilities are seen through many souls and they are powers of God and not Gods by themselves. They are misconstrued as Gods by humans. The souls showing His power are known as de:vatas.

Detailed Explanation : When God is in every form, it is only logical that every form belongs to Him. People get misled by seeing some of the powers that are there in the world, thinking that they run the universe. For example, the self-illuminating planet sun, also called as Surya Narayana is worshipped by some for being the life giver. Yes, he can be worshipped as God, as God is in him too. God is in the Moon, tree, bird – everywhere and everything. All the things that are visible, are different organs of God says the Ve:da. A person works through his organs. The sun is His eye, the space is His ear, and the wind is His nose. So, wherever His power is seen or experienced, instead of connecting those powers to God, some mistakenly call them as God, which is wrong. God will always be one. But His abilities are seen through many others. Each will be able to bring out His abilities in some respect of their own.  They are not Gods but are the powers of God. And they are called ‘de:vata:’ in Sanskrit (closely translated as divine beings in English). 

Ans: Each de:vata has a different role assigned to them, to help run the universe. If one has to categorize the de:vatas, it is said in the ve:da that there are 330 million(33 crores) de:vatas. 

Detailed Explanation: God has unlimited powers (infinite). Each de:vata is one aspect of the power of God. The human body is made of 5 elements and a de:vata body is made of light (te:jas). The de:vata of water is Varuna, Agni is the de:vata of fire, Va:yu is the de:vata of wind , Kube:ra is the de:vata of wealth, Ashwini kuma:ras are de:vatas for health and so on. Different de:vatas play different roles to help run the universe. It is similar to different ministers running different departments under a ruler in governing the kingdom.  They are superior beings than humans and hence, are misconstrued by some as Gods. The Ve:das say that de:vatas are the different parts of God – anga:ni anya:ha de:vata:ha  sa a:tma (sa a:tma is the inner soul which is God). God is inside them too, just like everyone else. All the de:vatas are His different parts and his limbs. It does not make sense to worship the part of a person instead of the person themself. If one has to categorize the de:vatas it is said in the ve:das that there are 330 million (33 crores) de:vatas.
