Let me explain aformentioned verse by dividing it into four parts: 1. If there is no control over sensual pleasure, you will have no wisdom. Have you heard that the love is blind? Scientists also belive that the statement is true. They did some study on people who are in love and found that they (lovers) see only positive things of their partners. Their (Lovers) evaluating part of mind gets weaker, and they can't evaluate their partner correctly. Isn't this the declination of wisdom? What is wisdom after all? Wisdom is something that helps you to see the truth in its real nature. It helps to see things as they are. However, if you are indulge in pleasure, you can't do that. So no control over pleasure, no wisdom. This is the first part of the verse. 2. No widom, no purification of mind. Mind get purified through wisdom only. If you can not see the truth as truth, you can't purify your mind. This is reality, whose who have been trying to purify their mind will understand this better. Wisdom of 'अनिच्चा" (अनित्य = impermanence) is the only way to purify the mind. 3. No purification of mind, no peace: If your mind is filled up with the negativiteis like anger, hatred, passion, lust, anxiety, inferriority complex, superiority complex, ego, jealousy, fear, insecuity etc, will you be able to sleep peacefully? Will you be able to stay at a place peacefully? You will sacre to death with yourself. You need company to run away from yourself. You need alcohol to forget yourself. You need drug to sedate yourself. You need TV. You need different means to forget yourself. As long as these impurities will present in you, there will be no peace in your mind. I will write more about it later. So, no purification of mind, no peace of mind is true. 4. No peace of mind, where the happiness will come from? रशान्तस्य कुत: सुख:म्? = मनै शान्त छैन भने, सुख कहाँ बाट आउछ? Happy state is the peaceful state of mind. If there is no peace, there is no happiness. Geeta is not talking about the external bulk peace. Peace is individual. Negativities of the mind bring tides in the mind. Peace is the state when waves of the mind sattle down. When all the excitements of the mind get sattled, you feel so calm, so tracquil , so satisfied, free from stress, free from pain, free from tension. This is happiness. If your mind is not peaceful, you are not happy. You believe it or not, these four are the truths. To get happiness, you have to control your sense organs whose tendency is to roll in pleasure.This is the essence of this verse. So tell me, can pelasure and happiness coexist? Are they same? I will write more in this later........... (We haven't lost ............... We are heading towards right direction........ I will finish by this weekend and you will get over all view what I want to say)
