The name “Kaliu” is derived from the Catalan word caliu.
The word has mainly two meanings:
First, it refers to the heat, e.g. in terms of fire. This usually means the hot embers.
Derived from this is the second meaning of affection and passion.

This word has fascinated me since I live in the region of Catalonia.
For me, Kaliu means light, warmth and to feel safe. The warmth and the light of the Mediterranean sun, the safety in the community of a fasting group.
