Arya: Pranam swani ji, my question is what is the concept of messengers in Vedas
for example concept of Islam is that Allah sends messengers to guide the human being, in Islam there are angels, satan, jinns, are in Vedas angels, jinns , satan, and sends God messengers? I thank for your answer.
Swami Ram Swarup: My blessings to you. You see, God is Almighty, as stated in several Ved mantras like Yajurveda mantra 40/8. Almighty means God has all unlimited powers. Therefore it is clearly mentioned in Vedas that God does not need any assistance to control the universe because God is independent and we all are dependent.

In this connection, I paste my article below:-

In Yajurveda mantra 31/7, it is clearly mentioned that the Vedvani emanates direct from God. Yagvalkya Rishi in his Smriti tells his wife Matryi that in the beginning of every creation this formless Vani emanates from formless Almighty God in the heart of four gentlemen selected by God from the previous creation in which they were topmost in Tapsya and good conduct etc. That is why automatically they are called Rishis with their names – Agni, Vaayu, Aditya and Angira. As the breath comes out from man similarly Ved mantras emanate from God. As outer breath is inhaled in the body so the Vedas are inhaled in God at the time of final destruction. {Please remember God is formless and has no mouth etc. This is an example and comparison only to enable us to understand the origination of eternal knowledge of Vedas otherwise neither it is exhaled nor inhaled from God.}

Further, in the heart of each of the four Rishis mentioned above, one Veda is originated without writing and without preaches. How? God is formless and Almighty, i.e., has all powers and does not require any assistance, i.e., God does not require any assistance from any Yamraj, any Yamdoot to get the soul out from any person, He does not require any assistance from any Indra, to shower water in the shape of rain, does not require any priest or preacher or Guru etc., to preach the religion to anybody because He is Almighty, He is always independent and His powers alone create and do all deeds etc., automatically.

Avtar

God is only one who creates the universe and no other can create the universe except God. Please think deeply is any one except God empowered for creation, etc.? The pious qualities of God are unlimited whereas qualities of soul, which resides in human body, are limited. That is why He is God. This fact is also mentioned by Rishi Patanjali in his Yog shastra sutra 1/24, “KALEASHKARAMVIPAKASHYAIHI APRAMRISHTAHA PURUSHVISHESHAHA ISHWARAHA” i.e., He who is not indulged in any sorrows/sufferings (kalesh), in any kind of deed (karma) and result thereof (vipakya), He is supreme in souls and is called Ishwar (God), whereas, soul is indulged in all the said matters according to deeds done in previous, and in the present life. So this is also a difference between God and souls and therefore soul can never be God based on the different qualities.

Amongst unlimited qualities of God, few may be enumerated-that God creates, nurses and destroys the universe. God is omnipresent, omniscient and omnipotent and Almighty, beyond description, beyond imagination, and beyond calculation. Nobody on the earth can deny such qualities, but these qualities are to be discussed and considered deeply and he who does the same is called MUNI as per Vedas and shastras.

Let us think over one quality of God – Being Almighty. Almighty means God has all powers and thus God, to control the universe and to do any kind of deed for the same, can not be dependent on another, at any cost, being Almighty. Again shastras say, which is a true saying too, that there must be reason behind for any creation, matter etc. God is a reason to create the universe. Parents are the reason to give birth to a child. Ravana took Sita forcefully which became a reason for war between Shri Ram and Ravana etc. So as per Vedas there must be a reason of avtar and after studying eternal knowledge of Vedas and thinking deeply, there seems no reason to take avtar by Almighty God. As in Yajurveda mantra 2/26, so is in Shwetashwaropnishad shlok 6/8 wherein it is mentioned that there is no reason to form a God and thus God is also formless i.e., nobody can make God but God creates universe from non-alive prakriti. Secondly the said Upnishad says that the
deeds of God of creation, nursing, and destruction of universe are eternal, natural, and automatic. So naturally God needs no avtar to destroy Kalyug, earth, or devils etc., being Almighty i.e., God has all powers and is independent. Not God but only His powers are enough to control, create, nurse, destroy the universe. That is why Upnishad says that God has no desire to create etc., but it is eternal and natural and this sort of desire is named “IKSHAN” and not desire to create etc.

Suppose God has to kill a devil and He takes avtar and God kills the devils by arrow etc. It means God is not Almighty and independent because God has taken help of Avtar (Human body) and arrow, gun, etc., which is impossible.

This all I have told based on fundamental law of eternal knowledge of four Vedas. Yet if anybody says about avtar then it is their own views and they are satisfied with their views and can not be commented because they could have been realizing at their own but so far as eternal knowledge of Vedas is concerned, Avtar is not possible.

Therefore, in Vedas there is no mention about angels, Satan, jinns/ghost etc.

Dinesh: How can I conform that God is there in real? In my studies God never help me please. You help me. How can a family member lose fat?
Swami Ram Swarup: My blessings to you. God helps those who help themselves, so everybody must first work hard following true path then we must pray God to help then He helps. If we see sun, moon, stars, air, water, mountains, the surprising creation of human body, then we must think deeply that Who has created it, we will find that it is not a work of human being. Secondly, without construction nothing can be constructed. So Who has created all the matters of universe. Four Vedas, shastras and all learneds give answer that Almighty God creates. So, based on the Anumaan (guess) proof we come to the conclusion that God is there and amongst divine qualities, these are also His qualities that He creates, nurses and destroys the universe. So, I advise you to please give full concentration on your studies, doing hard study and take care of your health. You’re a student and it is your mortal duty to study hard to please your parents to fulfill their desires and to make your future bright.

In regards fatness, I paste one of my articles –
One must awake early in the morning for a walk and light exercises. Take plenty of water, avoid always fatty and fried food. Do asan, pranayaam and meditation.

Take one glass of lukewarm water duly mixed one teaspoon of honey and juice of one lemon empty stomach and before brisk walk. Walk after dinner and go to bed in the night at least three hours after taking dinner. It all will be beneficial for the family member. Also take medical advises.
