सेवा
Seva is not charity. Charity can carry the weight of hierarchy — the giver and the given-to. Seva dissolves that. It is service performed as worship. The act of giving not because the other needs it, but because giving is your nature.
In the bhakti tradition, seva to the divine and seva to another person are the same act. To clean the temple floor with complete attention is the same as deep meditation. The ordinary becomes sacred when you bring your whole self to it.
