सिद्धौषधं जयति तेऽधररत्नपात्रे तापत्रयी झटिति मुञ्चति येन सिक्तम् । मन्ये तुषारकिरणं गुणलेशयोगादस्यैव वारिजविलोचन कल्कपुञ्जम् ॥९५॥
T: Oh lotus-eyed Lord, Śrī Varadarāja, Your gemlike lips are like the vessel is which is Siddhauṣadha, a surefire medicine for all ills. The Jiva bathed in that antidote is cleansed of the Tāpatrayam. A trace of that medicine's effectiveness is found in the moon on account of his being the waste residue left in the crucible after extracting the medicine.
Explanation: The Lord's gentle smile on His lips is the supreme remedy and antidote for all worldly ills called Tāpatrayam. Anything touched or wetted by that supreme smile sees that worldly ills leave it scattered instantly. In Tāpatrayam, the one element of physical ills is addressed by the moon known for his healing effects. This is attributed by the poet to the moon holding perhaps the waste residue from the crucible wherein the Lord's supreme medicine was prepared.
When oil is extracted from seeds, the waste residue is roughage holding but a tiny bit of the valuable oil. The waste left after extracting the essence is the residue called कुल्क. The poet exclaims that the moon himself, being merely the waste residue, is so effective in curing physical ills and giving much joy. Then imagine how delightful is the effect of the core essence, i.e. the Lord's smile!
