He excels who is of the same mind to the good-hearted, friends, enemies, the indifferent, the neutral, the hateful, the relatives, the righteous and the unrighteous.
He excels: He is the best among the Yogaarudhas. Samabuddhi is equanimity or evenness of mind. A Yogi of Samabuddhi has equal vision. He is quite impartial. He is the same to all. He makes no difference with reference to caste, creed or colour. He loves all as his own self, as rooted in the Self.

A good-hearted man does good to others without expecting any service from them in return.
Udasina is one who is quite indifferent.
A neutral is one who does not join any of the two contending parties. He stands as a silent spectator or witness.
The righteous are those who do righteous actions and follow the injunctions of the scriptures.
The unrighteous are those who do wrong and forbidden actions, who injure others and who do not follow the scriptures.
