As rain does never penetrate
a house that is well-thatched,
so lust does never penetrate
the mind well cultivated.
Explanation: When the house is well protected by a well-thatched roof, it is not harmed by the rain, because rain-water cannot seep though it. In the same way, the well-cultured temperament too does not allow passion to come through. Therefore, the well-cultured temperament cannot be penetrated by passions.
