Samacheer Kalvi 4th Tamil Guide Chapter 16 திருக்குறள் கதைகள்

தீயினால் சுட்ட புண் உடம்பில் தழும்பு இருந்தாலும், உள்ளத்தில் ஆறி விடும். நாவினால் தீயச் சொல் கூறிச் சுடும் புண், என்றுமே ஆறாது. சொல்லினால் ஆக்கமும், அழிவும் ஏற்படும். கோபத்தை அடக்கிக் காக்க முடியாவிட்டாலும் நாக்கை அடக்க வேண்டும். நாவை அடக்காமல், சொல்லத் தகாத சொற்களால் எடுத்தெறிந்து பேசுவதால், அச்சொற்கள் கேட்போர் மனதைப் புண்ணாக்கி, கடும் கோபத்தை உண்டாக்கும்.

இப்படி – நாவை அடக்காது ஒருவர் மாறி ஒருவர் தாக்கப்படுவதால் வேண்டத்தகாத விளைவுகள் ஏற்படும். அது உயிர் இழப்பையும்கூட உருவாக்கலாம். விளையாட்டாகப் பேசியது வினையாக முடிவதும் உண்டு.

மனித சமூகம் நாவைக் காத்தல் வேண்டும். அதனைக் காக்காவிட்டால், குற்றமான சொற்களைச் சொல்லி துன்பம் அடைவர். கதையில் ஒன்றைத் தெரிவு செய்து நண்பர்களுடன் இணைந்து நாடகமாக நடித்துக் காட்டுக. மாணவர்களே தாங்களாகவே செய்ய வேண்டும்.

சிந்திக்கலாமா?

அனுவும், பானுவும் சாலையைக் கடக்க, நின்று கொண்டு இருந்தனர். அப்போது மஞ்சள் விளக்கு எரிந்து கொண்டிருந்தது. அனு சாலையைக் கடக்கத் தொடங்கினாள். பானு, பச்சை விளக்கு ஒளிர்ந்தால் மட்டுமே கடக்க வேண்டும். பொறுமையாக இரு என்றாள். எது சரியான செயல்?
Answer:
பச்சை விளக்கு ஒளிர்ந்தால் மட்டுமே சாலையைக் கடக்க வேண்டும். பச்சை விளக்கு ஒளிரும்போது சாலையில் பிற திசைகளிலிருந்து வண்டிகள் வராது. ஆகையால் பானு கூறியதே சரியானது. சாலைவிதிகளைப் பின்பற்றுவதே சிறந்தது.

நீங்கள் நன்கு அறிந்த திருக்குறளுக்கு உம் சொந்த நடையில் கதை எழுதி வருக.
Answer:

கல்வியே நமது செல்வம்

ஓர் ஊரில் முத்தன் என்பவர் வாழ்ந்து வந்தார். சொந்தத் தொழிலில் ஈடுபட்டுக் கடினமாக உழைத்துச் செல்வந்தராக உயர்ந்தார். அவருக்குப் புகழினி, மதியழகன் என்ற இரண்டு பிள்ளைகள். பிள்ளைகள் இருவருக்கும் கல்விக்கு முதன்மை அளிக்காமல், தொழிலில் ஈடுபடுத்த எண்ணினார்.

ஆனால், தந்தையின் ஆலோசனையையும் மீறி கல்லூரி வரை இருவரும் படித்து முடித்தனர். முத்தனுக்குக் கல்வியின் மேல் பெரிய ஈடுபாடோ, விருப்பமோ கிடையாது. ஆகவே, சரியாகக் கல்வி கற்காத முத்தனை அவரது வியாபாரக் கூட்டாளிகள் ஏமாற்றி விட்டனர்.

இதனால் வீடு, வயல், ஆடு, மாடுகள் எனச் செல்வத்தை இழந்து ஒருவேளை உணவுக்கே துன்பப்படும் நிலைக்கு அவரும் அவரது குடும்பத்தினரும் ஆளாகினர்.

முத்தனின் பிள்ளைகள் இருவரும் இனியும் தாமதிக்கக் கூடாது என எண்ணிப் பல நிறுவனங்களுக்கு வேலை வேண்டி விண்ணப்பித்தனர். உரிய கல்வித்தகுதி பெற்றிருந்ததால், இருவருக்கும் நல்ல வேலை கிடைத்தது.

சில நாள்களிலேயே குடும்பத்தின் வறுமை நீங்கியது. முத்தன் கல்வியின் சிறப்பினை உணர்ந்து தமது கருத்தினை மாற்றிக்கொண்டார்.

குறள் : கேடில் விழுச்செல்வம் கல்வி ஒருவற்கு மாடல்ல மற்றை யவை.

விளக்கம் :
ஒருவருடைய நிலைத்த செல்வம் என்பது அவர் கற்ற கல்வியே ஆகும். அதனைத் தவிர வேறு எந்த செல்வமும் நீடித்து இருக்காது.
