I hear that he is determined to undertake a journey, but now our familiar companion is a stranger to us.

This profound couplet explores the paradox of emotional distance. The poet is saying that just hearing the news of someone's determined journey (safar ka azm) makes even the beloved's presence feel alien. The familiar comfort (aashna) of the beloved has become a stranger (begaana). It speaks to how profound change, or even the mere rumor of separation, can erode the intimacy of a relationship.
