INTRODUCTION 1.1 INTRODUCTION Purusartha-sunyanam gunanam pratiprasavah kaivalyam svarupapratistha va citi-sakter iti. (IV-34) (Patanjali) Patanjali's Yoga Sutra which talks about ultimate goal of human life is Liberation. That ultimate state of liberation is beyond the realm of intellect and therefore cannot be described in words. Liberation cannot be attained until purity arises. To attain purity one has to realize the self. Through pure knowledge is liberation, through auspicious knowledge is worldly happiness, through wrong knowledge is misery. If one who wants to go to Liberation, then one will have to adjust everywhere. Do not ever get involved in clashing with anyone - this is the biggest key to go to liberation. (Niruben Amin 2008). 1.2 HAPPINESS Human beings have born to attain happiness. Birth is not being for tortured by diseases. Happiness is the birth right of each and every individual. The creation is meant to endow happiness. No one outside can prevent from being happy. Not even God can prevent from enjoying bliss. When God has created this universe and men in order to live happiness and peace, anyone is certainly not going to prevent from being happy. Loosing own happiness is not through the faults of others. The responsibility is on who is losing the happiness through ignorance and in action of own. Disease represents only the reverse state of happiness. (Yogacharya Sundaram, 2004). Happiness is a mental or emotional state of well-being characterized by positive or pleasant emotions ranging from contentment to intense joy. Happiness and wellbeing is a state of mind developed by three basic interlinked elements such as physical or structural health, psychological or mental health and social health. (Ruchi Sundriyal and Ravindra Kumar, 2014) Man has disturbed the balance between the internal and external activities, a balance which is necessary for a successful and happy life,
