Sarg 37/1 - Birth of Baali and Sugreev 

Raam said to Agastya Muni - "Hey Rishivar, You told that Baali and Sugreev's father's name was Riksh Raaj. What was their mother's name? And why these names were given to them?" Agastya Muni said - "Hey Raghu Nandan, Once Naarad Jee came to our Aashram wandering around. When we asked this him, he said - "On the peak of Sumeru Parvat, where Devtaa live, there is Brahmaa's divine court in 100 Yojan area. Once when Brahmaa Jee was practicing Yog, two drops of tears fell from His eyes. Brahmaa Jee took them in His hand and wipe His hand with His body. Later when he shook His hand then one drop fell on the ground.

A Vaanar was born from that drop. Brahmaa Jee said to him - "Look Vaanar, you stay on the peak of that mountain. After some time there will be something good to you." That Vaanar went away there and lived there on fruits, and flowers. Now this Vaanar used to offer beautiful flowers and honey on the feet of Brahmaa Jee. Thus a long time passed.

One day this Vaanar got very thirsty, so he went to look for water to the north side of Sumeru Parvat. There he found a pond, and as he bent down to drink water from that pond, he saw his shadow in the water. He thought, "Who is this my enemy here? I will kill him." And he jumped into the pond to kill him. But when he came out he found himself in the form of a beautiful woman.

At that time Indra was coming back from Brahmaa Jee. By chance Soorya Dev was also came there on his way to somewhere. Both Devta saw that beautiful woman and had a desire to have her. Indra's semen got ejaculated and fell on the head of that woman. This produced a Vaanar. Because the semen fell on her hair (Baal in Hindi language) he was called Baali.

Soorya's semen fell on her neck (Greevaa in Hindi language). This also produced a boy who was called Sugreev because of the semen falling on her Greevaa. Indra gave a very qualitative chain to Baali and Soorya appointed Hanumaan for Sugreev's help. So Hey Raajan, After this that woman again became Riksh Raaj. 

Then Riksh Raaj went to Brahmaa Jee along with his two sons. Brahmaa Jee assured him and sent His messenger with him to Kishkindhaa Nagaree saying - "There live Vaanar and human beings of four Varn. Invite all of them and crown him as king there." So that messenger brought them to Kishkindhaa Nagaree, crowned Riksh Raaj as king there. Thus Riksh Raaj, Baali and Sugreev's father, is the king of all Vaanar of the whole world.

Sarg 37/2 - Raavan Talks to Sanat Kumaar

Raam said - "Hey Munivar, Because of your grace we heard this interesting and wonderful story. When Baali and Sugreev are the sons of Indra and Soorya then why shouldn't they be so much glorious and gracious." Agastya Jee said - "Now I will tell you the reason as why Raavan abducted Seetaa. Listen to it.

In Sat Yug, once Raavan went to Brahmaa's son Sanat Kumaar and asked - "Hey Tapovan, By whose help Devtaa win in war? Who do Yogee meditate? Who do Braahman worship? Hey Maharshi, please explain me in detail." Sanat Kumaar said - Hey Putra, Who sustains everybody in this world; from whose navel Brahmaa Jee has born; on whom we all depend; Dev Gan win Raakshas with the help of same Vishnu Bhagvaan."

Raavan again asked - "Hey Muni Shreshth, Whoever Raakshas have been killed by Devtaa so far, what has happened to them?" Maharshi said - "Hey Raavan, Whoever have been killed by Vishnu, they get Moksh (salvation). They don't come back to Prithvi. Even the enmity of Vishnu is also good." Hearing this Raavan started thinking as how could he have a fight with Vishnu Bhagvaan.
