Dear Prof. Herath: Nice question you had put. I must congratulate you for your thrust to know the happiness. If you follow Vedic Science or Indian Scriptures, the Happiness is a inner state of consciousness. It is something like we are trying to find the shadow of individual in absence of Sun. It is a thrust which makes you focus, understandable and beyond words. You are from the World of Lord Buddha. What he said very rightly Appo Deepo Bhav. Be a lamp to Thyself and the it will be a state of eternal happiness. You can also define the Happiness is the absolute absence of Sorrow. Now if I am not wrong, you are in the process of framing the Happiness from Research perspective. although i am in process of writing a book on Law of happiness. for your kind reference you can watch Swami Sarvapriyananda at IITK: Happiness - Vedanta and Positive ...lecture of Youtube. hope it will more pleasurable that we can meet some day and discuss more. With warm regards Prof. Abhay
I recognize that the source of all happiness comes from my Creator and so I am most happy when I know that I am doing God's will in my life in giving thanks for blessings received such as breakthroughs in trying situations when I am victorious.
