The contacts of the senses with the objects, O son of Kunti, which cause heat and cold, pleasure and pain, have a beginning and an end; they are impermanent; endure them bravely, O Arjuna.

Contacts of the senses with their objects, son of Kunti, give rise to cold and heat, pleasure and pain. They come and go and do not last; bear them patiently, descendant of Bharata.

Having spoken of what endures, Krishna turns to what passes. Experiences of cold and heat, pleasure and pain arise from the meeting of the senses with their objects (mātrā-sparśa). They come and go and are not lasting, so Arjuna is told to endure them (titikṣā). This is practical advice as much as philosophy: a warrior on the battlefield must bear discomfort and emotion without being ruled by them. The same discipline of patient endurance applies to grief, which also belongs to the passing play of experience.
