upyamanam muhuh ksetram
svayam nirviryatam iyat
na kalpate punah sutyai
uptam bijam ca nasyati
evam kamasayam cittam
virajyeta yatha rajann
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
My dear King, if an agricultural field is cultivated again and again, the power of its production decreases, and whatever seeds are sown there are lost. Just as drops of ghee on a fire never extinguish the fire but a flood of ghee will, similarly, overindulgence in lusty desires mitigates such desires entirely.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
If one continuously sprinkles drops of ghee on a fire, the fire will not be extinguished, but if one suddenly puts a lump of ghee on a fire, the fire may possibly be extinguished entirely. Similarly, those who are too sinful and have thus been born in the lower classes are allowed to enjoy sinful activities fully, for thus there is a chance that these activities will become detestful to them, and they will get the opportunity to be purified.
