From the back of the book:

Samadhi is the transcendental experience of completeness and fullness, devoid of all duality, and the end of all relative existence. It is the culminating point in the spiritual quest and the fulfilment of human destiny. One who had realized samadhi becomes silent, wise and illumined and blessed with eternal contentment and perennial joy. For the rare one who sees the all-pervading, tranquil, blissful atman there remains a feeling of having attained all that was ever to be known, and life is guided by the realization that one self pervades everyone and everything.

Maha Samadhi: Antardhyana is compiled from the teachings of two yogic masters, Swami Sivananda Saraswati and Swami Satyananda Saraswati. Their remarkable insights come from their personal, direct and everlasting experience of the Absolute. This exceptional book is an inspiration to all those who seek to understand and experience.
