The Title says it all and most importantly do not tell lies. One lie will need another lie to cover-up. Then it will multiply simultaneously and there's no end to it. Regretting later on, will be too late. No one can help you or no one will want to help you being a liar.
Think deeply do you ever experienced it before? Do not lie again and don't think it's alright to lie about whatever matters or issues. There will always be Causes and Effects and that's Karma. Karma will happen anytime, in any forms too. You can't avoid or escape and no one can helps you. What You Sowed Is What You Reaped. Some people are too habitual in lying or deception. Thinking it's fun to lie or deceive and in the end, trying to repent but it's too late.
It's a piece of advice from Ajahn Singha Thong.
