In plain words
'No talk of peace at all; ready for war,' said Arjuna. By the time he saw the form, attachment and the sense of 'mine' had taken root in his heart. This very attachment and sense of 'mine' are bringing man down. Attachment and the sense of 'mine' must be there. But there must be a limit. Since you have joined this place at this age, and since you live in this holy atmosphere, you must develop good qualities, good conduct, good behaviour and good reflection.
