Sex life is compared to the rubbing of two hands to relieve an itch. Grhamedhis, so-called grhasthas who have no spiritual knowledge, think that this itching is the greatest platform of happiness, although actually it is a source of distress. The krpanas, the fools who are just the opposite of brahmanas, are not satisfied by repeated sensuous enjoyment. Those who are dhira, however, who are sober and who tolerate this itching, are not subjected to the sufferings of fools and rascals.
