|Chapter 1: Observing the Armies on the Battlefield of Kurukshetra|
tan samikshya sa kaunteyah
sarvan bandhun avasthitan
vishidann idam abravit
When the son of Kunti, Arjuna, saw all these different grades of friends and relatives, he became overwhelmed with compassion and spoke thus.
One of the basic qualities of a devotee is compassion. Seeing all those who are near and dear to him and the prospect of having to kill them invokes this compassion in Arjuna. However this should not be confused with sentimentality, which is more on a mundane, emotional level. Arjuna is soft-hearted, compassionate and logical. He is knowledgeable of the scriptures, cultured and intelligent.
