When Lord Shiva was engaged in severely austere meditation, Cupid, the demigod of lust, threw his arrow of sex desire. Lord Shiva, thus being angry at him, glanced at Cupid in great wrath, and at once the body of Cupid was annihilated. Although Lord Siva was so powerful, he was unable to get free from the effects of such wrath. But in the behaviour of Lord Vishnu, there is no incident of such wrath at any time. On the contrary, Bhrgu Muni tested the tolerance of the Lord by purposely kicking His chest, but instead of being angry at Bhrgu Muni the Lord begged his pardon, saying that Bhrgu Muni’s leg might have been badly hurt because His chest is too hard. The Lord has the sign of the foot of bhrgupada as the mark of tolerance. The Lord, therefore, is never affected by any kind of wrath, so how can there be any place for lust, which is less strong than wrath? When lust or desire is not fulfilled, there is the appearance of wrath, but in the absence of wrath how can there be any place for lust? The Lord is known as apta-kama, or one who can fulfil His desires by Himself. He does not require anyone’s help to satisfy His desires. The Lord is unlimited, and therefore His desires are also unlimited. All living entities but the Lord are limited in every respect; how then can the limited satisfy the desires of the unlimited? The conclusion is that the Absolute Personality of Godhead has neither lust nor anger, and even if there is sometimes a show of lust and anger by the Absolute, it should be considered an absolute benediction.
