Chapter-XXII: Vishwamitra’s yagnya
When Vishwamitra asked Ram to come with him to save his Yagnya, King Dashrath was not ready to son his son, who had recently returned from Gurukul.
He asked the munivar, if he himself could go. But the tapasvi denied his any other help than taking Ram with him.
Ram appeared with his bow and arrows and said,"Father I wish to go to the Rajarishi's yagnya to help him." King Dhashrath was shocked by his son's decision, but his eyes widened even more when he heard another voice say,"I will accompany my brother." This was the moment when Dhashrath realized that the twins were born to help their brothers.
He noticed the clear love for Ram on Lakshman's and for Bharath on Shatrughan's face. These children were made of the same Charu(the holy porridge given by gods) and inseparable. He felt proud of Laksman, but was afraid to send either of them. But the Kulguru Vashishta advised him to send them.
