how does rama show sugriva that he is a great warrior
Vali (Ramayana) Sugriva is very scared of Vali and he is full of doubts that Rama could kill him. He tells him many incredible stories of Vali's power. As proof, he shows Rama a hole in a saal tree which Vali had made in one shot. When it is Rama's turn, he penetrates 7 trees of saal in a row with 1 arrow. After going through the trees, the arrow even makes a strike on a huge rock and splits it into pieces. Sugriva is happy and says, "O Rama, you are great."
Chola dynasty Rajaraja Chola I and Rajendra Chola I were the greatest rulers of the Chola dynasty, extending it beyond the traditional limits of a Tamil kingdom.[38] At its peak, the Chola Empire stretched from the island of Sri Lanka in the south to the Godavari-Krishna river basin in the north, up to the Konkan coast in Bhatkal, the entire Malabar Coast in addition to Lakshadweep, Maldives, and vast areas of Chera country. Rajaraja Chola I was a ruler with inexhaustible energy, and he applied himself to the task of governance with the same zeal that he had shown in waging wars. He integrated his empire into a tight administrative grid under royal control, and at the same time strengthened local self-government. Therefore, he conducted a land survey in 1000 CE to effectively marshall the resources of his empire.[52] He also built the Brihadeeswarar Temple in 1010 CE.[53]
