Sage Of Kanchi (Jagadguru Sri Chandrasekharendra Saraswati Mahaswamigal (20 May 1894 – 8 January 1994)) states that no desire means no anger and no sin.
The cow sees its reflection in the mirror and charges it imagining it to be another cow. If a man sees his own image thus, does he think that there is another person in the mirror? He is not perturbed by his image because he knows that it is himself. Similarly, all that we see is one and the same thing. Desire springs from our belief in the existence of a second entity, and it causes anger, which, in turn, plunges us in sin. A new birth becomes inevitable now. If we are enlightened enough to perceive that all objects are one, there will be no ground for desire. There must be an object other than ourselves, a second entity, to be desired. No desire means no anger and no sin. In this state there will be neither any "doing" nor any birth. And, finally, there will be no sorrow.
What is the cause of desire? Desire arises from the belief that there is something other than ourselves and our being attached to it. In truth it is the one Sivam that manifests itself as everything.
Religion is the means of realizing dharma, artha, kama and moksha. These four are called purusharthas.
In Tamil, dharma is called “aram”; artha is known as “porul’; and kama and moksha are called “inbam, “and vidu respectively. “Artha” occurs in the term “purusharthas”, but it is itself one of the purusharthas? What a man wants for himself in his life - the aims of a man’s life - are the purusharthas. What does a man want to have? He wants to live happily without lacking for anything. There are two types of happiness: the first is ephemeral; and the second is everlasting and not subject to diminution. Kama or inbam is ephemeral happiness and denotes worldly pleasure, worldly desires. Moksa or vidu is everlasting happiness, not transient pleasure. It is because people are ignorant about such happiness, how elevated and enduring it is, that they hanker after the trivial and momentary joys of kama.
Our true quest must be for the fourth artha that is vidu or moksa. The majority of people today yearn for the third artha that is kama. When you eat you are happy. When you are appointed a judge of the high court you feel elated. You are delighted when presented with a welcome address by some institution, aren’t you? Such types of happiness are not enduring. The means by which such happiness is earned is porul. Porul may be corn, money, and house. It is this porul that is the way to happiness. But the pleasure gained from material possessions is momentary and you keep constantly hungering for more.
