A Chassid does not mean that there was a time when he was a Chassid.

חסיד אין פירושו שהי' זמן שהי' חסיד

This expression emphasizes that being a Chassid is not just about having been a Chassid at some point in the past, but rather it is about continuously living and embodying the qualities and commitments of a Chassid in the present. The statement suggests that a true Chassid is someone who consistently applies the teachings, values, and practices of Chassidus throughout their life, rather than resting on past achievements or experiences.

In other words, the identity of a Chassid is not static or tied to a particular period, but is an ongoing, active commitment to the path of Chassidus, reflecting a continuous effort in spiritual growth and devotion.
