Eminent researchers and modern thinkers like Eric Fram, Harry S. Sullivan and Dr. Henry Lindlahr, etc consider that we can improve our physical and mental health by linking our consciousness with some divine source, angelic power or cosmic consciousness. They regard that if we deeply contemplate over a specific object or focus, our mind gets connected to the corresponding source or domain, as a radio-station gets connected with the radio sets through microwaves. Such mental conjunction or emotional linkage with divine sources bestows not only spiritual but also mental and physical benefits. Human mind is like an ultra-sensitive wireless receiver, which, unless focused on a specific domain, keeps receiving thought-waves from all directions, all the time. What kind of thoughts it will generate depends on what it has been receiving and storing in general. Thus, focusing and linking it with specific kinds of thoughts through contemplation and meditation is the most effective way of conditioning, training and orienting the thought process. Upasana gives an added advantage of emotional illumination.

Sagacious and bright thoughts induce a matching ambience wherever they are generated and spread intensely. Noted thinker U. Sinclair elucidates this fact further in his book “The Mental Radio” and explains that devotional meditation (upasana) is a complete process of refinement of personality; anyone who follows its practice sincerely would develop excellent personality and also inspire others in his company. He can transmit his (spiritually energized) thoughts without any physical medium. The intense field of such thoughts possesses the power to influence people’s minds and the subtle environment around.
 
Renowned Psychologist C. G. Jung regards upasana as a necessary requirement of human life. In his views, the methods of devotional worship and meditation preached under different religions of the world all provide useful and essential basis and support for healthy and overall development of personality. According to him, the total number of psychological disorders and problems cured by the psychiatrists and psychologists across the globe would be nothing as compared to the positive effects of the simple religious practices of devotion.
