Jai Sri Ganesha,
Definition of the virtue is not that easy, neither is it fixed in any format,
Virtue is an eternal subject, starting in roots from the eternity of self that leads the self to the path unto self and merges within its subtle truth,
The practice of charity could be an aspect of it if totally bare from the lineage of vanity or ego or name game for the hidden cause,
Though charity is a part of service many are involved for varying chapters to gratify themselves yet the disinterested service to the truly depraved to survive may help one to relocate self eternally,
May Lord bless all,
Thanks, please
