Dear Souls,
Brahma and the Brahmins are the first who were influenced by Satan(vices). Hence Brahma is shown with many hands. Out of these Brahma is No. 1. He is the first Brahmin.
In a Kalpa, the high powerful souls descend first to take the highest seat. So- these Brahmin souls become deities in heaven and they enjoy it since it is their own earned property. As time passes, the power in the soul(deities) reduces. Since the soul is in contact with body for 2500 years, the soul gets influenced by the body and becomes body-conscious. Their action becomes impure and it is called as sin. It is the beginning of hell. The less powerful souls had not earned (put real effort) and hence do not get real(pure, the one in which there is no pain at all) property. Real means truth. So if a soul remains in soul (true) conscious, it is true property. This is possible only in heaven.
So when hell begins, it is time for other souls to descend. The reason is all these souls were interested in just hell. They have not remembered heaven at all! They had not put effort in forgetting the hell and remembering heaven (in the previous Kalpa). They had attachment just in hell. So they get property of just hell. All these things happen naturally.
Has Brahma or Brahmins caused sorrow to others? No. Because each soul gets just happiness when it descends from Paramdham initially. So, these souls were getting just happiness initially. But since their power is less, they get influenced by the hell and vices and start committing sin. Then such a soul gets fruit for its own action. But what these souls do? Since they have a lot of attachment to hell, they try to take property from these (impure deity) souls. In this way, the other religions looted deity religion’s wealth (after Copper Age) and establish their kingdom. Now you decide who is satan.
ACTUALLY THERE IS NO SATAN AT ALL. THE WEAKNESS CAUSES PAIN. SO THESE WEAK QUALITIES ARE CALLED AS SATAN.
I think these Brahmin souls commit sins mainly by lust action in 63 births. They do not harm other religion souls. They harm themselves (may also be fighting with each others, Indian Kings were fighting with each others in Kaliyug. In this way, they become weak. Then they are attacked by other religions. Hence other religion souls’ sins increase more. Since these souls are harmless to others, they get highest seat in the drama. Also they get a chance to burn their sins by remembrance of God and get saved from punishment; The real lucky souls!
*Since they stay in body for a long time, they become highest impure.
*Since they become highest pure, they get the capacity to remain in body for a long time. They get the capacity to accommodate more sins and still play role till the end of Kalpa. They never get tired in their roles. Hence these souls are called as hero actors.
