MR. RAVINDRA MOHAN CHOPRA (born 14th January, 1934 in Hafizabad, West Punjab) is a worthy son, inheriting dedication to social work and literary disposition from his worthy father Late Dr. Hira Lall Chopra, M.A., (Punjab), D. Litt. (Tehran), the well-known litterateur and social worker of Kolkata.

In his professional field he had been a top executive with Turner Morrison Group of Companies which he joined in 1962.

Twilight, in general terms, is the illumination by the sunlight scattering in the upper atmosphere, illuminating the lower atmosphere when the surface on earth is neither completely lit nor completely dark, which can be construed as a meeting of the light of the sun and the light of the human sacrifice. The purpose of human life is to sacrifice its whole towards realizing its true divine higher self that which is verily the soul. The delight implies inner fathomless peace, and inner fathomless happiness in merging the soul in oneness with the divine blissful Supreme Infinite Soul. When the micro cosmic individual human soul and the macro cosmic eternal Infinite Soul merge in oneness thereat reposes Truth. Viewing objectively, one realizes that spiritual wealth is the real inexhaustible wealth. Divine knowledge is the real knowledge. The best course available to human individual is: realize the Eternal Soul and attain freedom, perfection and immortality.
In this book I have tried to explain as to how all this can be achieved by individuals in as simple a manner as possible. This monograph, for easy comprehension, has been divided into three sections.
