After doing nav and puja, there seems to be a custom to do puja for the left toe. Is this correct and what is the reason for this.
Answer
If you mean the left toe of the Jina idol, then yes, in some Jain ritual traditions this may be done, but it is not a universal or compulsory Jain rule.Explanation
This kind of act is usually symbolic. It is done to show:- Humility before the Tirthankar
- Respect for the whole form of the Jina
- Completeness in devotion
- Focus of mind during worship
The toe itself is not being worshipped for its own sake. The real intention is devotion to the pure qualities of the Jina and the inner attitude of reverence.
Different Jain traditions and temples may follow different puja paddhatis. So if a temple or sangh includes this as part of its ritual, it is usually a local or traditional practice, not a mandatory rule for all Jains.
Spiritual Understanding
In Jain Dharma, the outer ritual is meaningful only when it helps reduce:- ego
- attachment
- carelessness
- disrespect
So even small ritual gestures are meant to build vinay and bhakti. The value lies in the inner भावना, not in the physical object itself.
