There is really no point in blaming philosophers for only preaching that which you do not want to practise. I mean, seriously, if you truly wanted to do something and a philosopher eggs you on to do that exact same thing, would you treat him respectfully as a sage? Like, if someone were to tell you, 'Eat, drink and be merry', do you treat him with the respect due to a wise man? (Ah, No, No, No! Don't tell me you do because you can use him to counter all those others who push you to abstinence. For him to BECOME someone worthy of being pushed as a counter-argument, he has to have done something ELSE.) So, yeah, what the philosophers say generally tend to be unpalatable.
So, here goes Tiru with his
Orumaiyul aamaipol aindhadakkal aatrin ezhumaiyum yemaappudaiththu - Tirukkural
Like the tortoise which pulls in its five protrusions into its shell in times of trouble, if you can control your five senses in the face of illegitimate temptation in one birth, it will benefit seven births - Loose Translation
In a way, I have taken liberties with the translation. See, the Kural would only say, 'Like the tortoise, if you can control your five in one birth, it will benefit your seven births'.
But if the tortoise permanently shrunk its limbs and head into its shell, it is hardly likely to live, is it? The tortoise does that only in times of danger. So, if YOU are to do the controlling of your senses, WHEN should you choose to do that? It's not like Tiru is asking you to wilfully play blind or deaf or whatever. So, then? It's only in times of temptation. But, then, are ALL temptations likely to be dangerous? Perhaps not. I have taken the position that only illegitimate temptations are a problem. (But, yes, if you will classify as temptations ONLY those desires that are illegitimate, then you can forego the adjective.)
Controlling anything does not necessarily mean stopping it. When you control the flow of water, you do not necessarily always completely close the tap, do you? Tiru is not a saint, only a philosopher. AND he is a practical chappie. So, what he means is only that you should control the ways in which you use your senses, not that you should apply total restraint and become a Rishi.
But, yes, he does not say you should NOT apply the restraint, either. He does prescribe restraint though not abstinence. But the restraint he prescribes here will only benefit you for seven births. Whereas the abstinence of a sage is supposed to take the soul to nirvana and thus escape the cycle of births and deaths in toto.
If you do not believe in this theory of reincarnation, you can apply it like the whole world seems to be applying the theory of karma. 'Karma will get you', 'Karma is a bitch' and so on, meaning that, even if there is only one life, karma will keep lurking around and 'get' you, sooner or later.
Nowadays, Karma is in a hurry and does not have the patience to wait around for the next birth. This kural, being a spin-off of the karma theory, will also mean that the benefits of the karma it prescribes will redound to you in this birth. IF, however, you fail to live by it...
BEWARE. Karma will get you in this birth! Makes me feel better that I actually believe in reincarnation, after all!
