Blood is the vital breath of living beings; by its depletion, the digestive fire is depleted,
And vāta increases; therefore, one should employ nourishing therapy with discretion.
Gradually, like an anthill, a nodule [forms], likewise with many minute openings
Abounding in pain, burning sensation, itching, and moisture; this is valmīka, caused by all [doṣas].
