What the two compartments mean
Munmudi
The front portion is for the Lord: Ney-thenga, offerings, and items meant for worship. This side must be handled with special reverence.
Pinmudi
The rear portion is for the pilgrim's limited essentials and travel-use items. This is not a place for unnecessary weight or luxury.
Spiritual meaning
The Irumudi teaches both surrender and restraint: what belongs to the Lord goes before us, and what belongs to us becomes secondary.
