Swāmī Rāma was born Brij Kiśore Dhasmana or Brij Kiśore Kumar,to a northern Indian Brahmin family in a small village called Toli in the Garhwal Himalayas. From an early age he was raised in the Himalayas by his master Bengali Baba and, under the guidance of his master, traveled from temple to temple and studied with a variety of Himalayan saints and sages, including his grandmaster, who was living in a remote region of Tibet. From 1949 to 1952 he held the prestigious position of Shankaracharya of Karvirpitham in South India. After returning to his master in 1952 and practising further for many years in the Himalayan caves, Swami Rama was encouraged by his teacher to go to the West, where he spent a considerable portion of his life teaching, specifically in the United States and Europe. He is especially notable as one of the first yogis to allow himself to be studied by Western scientists. Swami Rama authored several books in which he describes the path he took to becoming a yogi and lays out the philosophy and benefits behind practices such as meditation. One of the common themes expressed in such books as "Enlightenment Without God" and "Living with the Himalayan Masters" is the ability of any person to achieve peace without the need for a structured religion. He was critical of the tendency for yogis to use supernatural feats to demonstrate their enlightenment, arguing that these only demonstrated the ability to perform a feat.
Not sure what "Type" of Hindu Swami Rama is, but I'd peg him as highly Samkhya influenced, compared to most modern Hindus. I say this because in Rama's vision, the Self either is, or expresses itself through the unconscious mind. Even consciousness is a product of matter and is subject to Karma. The theory is almost atheistic, and more concerned with the relationship between consciousness and unconscious processes than it is with supernaturalism.
The concept of the unconscious mind or soul or atman in this book is a very powerful one, within the constraints of naturalism. It is capable, with due training, to bypass conscious experience, and access this unconscious mind, in which even such concepts as ego time and space, vanish from perception and you simply exist in some indescribable-other-than-through-poetry state of samadhi. You realize your Self in this state.
The book posits meditative practices, both as a dedicated activity (raja yoga) and as a part of daily practice (karma yoga) as a way of gaining access to parts of the mind which are normally inaccessible. Once you have access to those processes, or are a self realized yogin, (same thing), you can determine your own desires instead of being driven by the inertia of the consequences of past action, compulsions, irrational fears or destructive tendencies, etc.
This is a Swami who has by the way, empirically demonstrated under scientific conditions, his ability to control quite a few of his autonomic processes. He has demonstrated at least that it is possible to bring normally inaccessible parts of our human nervous structure under conscious control.
To be free of the automatic compulsions of our unconscious brain, and to instead control and harmonize both levels of thought is to be truly spiritually free in Rama's sense. This is Liberation (Moksha) in Rama's paradigm (Which I could be completely wrong about because hes written many more books than this one and I'm also probably impressing my own belief system onto it.)
There are some interesting meditational techniques in here, especially for those without much experience. For instance, many people feel very distracted while meditating and expend much effort trying "clear their mind". Instead, try examining and analyzing the distracting thoughts and introspecting based on them. They'll go away eventually.
It also works heavily in the tamas, sattva, and rajas paradigm, another Samkhya fetish, so I enjoy it.
An authoritative exposition on the subject of karma, the book succinctly explains what is karma, the law of karma, and its significance in spiritual advancement.
Renouncing karma is not possible. Whether one follows the path of action or of renunciation, karma is inevitable. In turn, karma creates bondage, by which one becomes entangled in the endless cycle of birth and death. It is possible to extricate oneself from this bondage. But first, one is required to understand the strands that form the chord of karma. Each strand must be effectively managed so as not to further strengthen bondage.
Means of achieving freedom from bondage is offered in practical terms. A primary consideration would be to study the mind and learn how it functions. One becomes aware of the thinking process as the first step in learning how not to identify oneself with the thoughts. Introspection, internal dialogue and other instruments in refining our understanding of karma, and alleviating bondage is outlined. The importance of meditation and its three-fold purpose is particularly emphasized. The teaching is brought together in the final chapter, Liberation and Selfless Action. It speaks of the power in performing actions that are selfless. It is the true means of liberation.
This book is a gem for those who wish to understand karma in simple, direct language. The author, an accomplished yogi and a true master, unravels the complex cycle of karma and bondage, explaining them in a manner that is easily understood by readers.
