Answer

In Jain practice, Vāsakṣep Pūjā should be done on a clean and properly prepared idol/area, not casually over the previous day’s kesar.

So, if there is old kesar from the previous day, it is generally proper to respectfully clean it first according to your temple’s maryādā, and then perform Vāsakṣep Pūjā.

Explanation

In Jin Pūjā, cleanliness and reverence are very important. Before offering any new dravya such as vāsakṣep, the idol and pūjā place should be kept clean and pure.

However, exact practice can vary depending on:

• Temple maryādā
• Derāsar tradition
• Śvetāmbara or Digambara practice
• Instructions of the pujari, trustee, or guru bhagwant

If the idol already has kesar from an earlier pūjā, one should not act carelessly. It should be cleaned respectfully, and then the next pūjā should be done.

Spiritual Understanding

Cleaning before pūjā is not just physical cleanliness. It reflects inner purity, humility, and devotion. Jain Pūjā is done with the bhāv of honoring the Arihant Bhagwan, so every action should be done with awareness and respect.

Takeaway

Yes, clean first respectfully, then do Vāsakṣep Pūjā, unless your local temple maryādā specifically instructs otherwise.
