Positive psychology is a relatively new field that examines how ordinary people can become happier and more fulfilled. Positive psychology is a science of positive aspects of human life, such as happiness, well-being and flourishing. Indian psychology is an approach to psychology based on the Indian ethos. Indian Psychology is essentially positive and rooted in the consciousness-based Indian worldview, yoga and a life-affirming spirituality. Human life is a journey of the soul which resides in the human body. Indian psychology highlights the pathway to make this journey easy and the ultimate goal of liberation of the soul (moksha) achievable through yoga, meditation and prayer. Humans are made of the body, mind, intellect, ego and soul and only soul can help to attain ultimate happiness and bliss through spirituality. The present paper is an attempt to explain that both positive psychology and Indian psychology focus on human happiness and their unique strength; and discusses how goals of positive psychology can be achieved through the rich Indian spiritual heritage. Indian psychology and spirituality share a framework that human has enormous potential hidden in its being. Indian scriptures (Vedas, Upanishads, Yoga, Bhagavad Gita) and spiritual practices (Yoga, meditation and prayer) help to discipline the mind to achieve balance, (samyavastha) to overcome the hindrance in the pursuit of happiness and to improve the qualities of different roles we play in our lives. In this way the Indian spiritual practices have important implications for the achievement of goals of Positive Psychology i.e. wisdom and knowledge, courage, humanity, justice and transcendence and makes life worth living.

Fortuitous exposure to high temperatures initiates reaction in energetic materials and possibilities of such event are of great concern in terms of the safe and controlled usage of explosive devices. Experimental and numerical investigations on time to explosion and location of ignition of a phase changing polymer bonded explosive material (80 per cent RDX and 20 per cent binder), contained in a metallic confinement subjected to controlled temperature build-up on its surface, are presented. An experimental setup was developed in which the polymer bonded explosive material filled in a cylindrical confinement was provided with a precise control of surface heating rate. Temperature at various radial locations was monitored till ignition. A computational model for solving two dimensional unsteady heat transfer with phase change and heat generation due to multi-step chemical reaction was developed. This model was implemented using a custom field function in the framework of a finite volume method based standard commercial solver. Numerical study could simulate the transient heat conduction, the melting pattern of the explosive within the charge and also the thermal runaway. Computed values of temperature evolution at various radial locations and the time to ignition were closely agreeing with those measured in experiment. Results are helpful both in predicting the possibility of thermal ignition during accidents as well as for the design of safety systems.
