Mitra, Sakha, Sahchar are just words which describe this Pavitra relationship between two souls. Without any Bandhan or bondages.

In both of the Human incarnation, Shri Hari Vishnu taught us the value of friendship and duties of a Friend.

As Ram, He was friend with Guha, Sugreev and Vibhishan.
Shri Ram promised to help out his friends from distress and fulfilled the promise. With Guha, the relationship was pure as gold and filled with devotion.

Krishna was friend Sudama and Arjuna. When Agni asked Shri Krishna to ask for any boon after Khandav Dahan, Krishna only asked that his bond with Arjuna keep increasing and they remain friends till the end.

He helped Sudama and got him out of poverty. He did it without asking anything in return.

We can learn every lesson of life by just following our deities and God.

Jai Shri Ram. Jai Shri Krishna
