The text contains 112 "means," traditionally called dharanas, or "methods of union" (yukti) with God. The text makes it clear that everything can become a means to attain the supreme reality. No aspect of life is excluded from it, since the very core, the deep dimension of all, is God. It may be the one-pointed view of the empty sky, the intense experience of joy, of eating, of sexuality, of music, of intense surprise—in every moment there can occur this sudden "tilting" of the picture, and the subtle, hidden dimension of reality becomes visible. This happens also in great fear, bitter sorrow, or intense pain, because these states spontaneously can direct consciousness to one-pointedness. The text describes the goal of all these means as attainment of "pure consciousness" or, as the title says, the "[mystical] knowledge of Bhairava" (vijnana bhairava). Other descriptions are: becoming one with Shiva, merging in God, and revelation of God. Bhairava is here the name of the ultimate reality, which is both transcendent (the Shiva-aspect) and immanent (the aspect of the goddess Shakti, Shiva's energy). In Christian terms, we would call this highest goal unio mystica. At this point Christians may object: Can this highest aim be reached by methods? In spite of old prejudices about "self-salvation," the main factor in this tradition, too, is grace (anugraha). Without the free play of God's grace, represented by his energy or spirit ("Shakti"), there can be no fulfillment. This becomes clear even by the structure of the verses itself: A verse describes very briefly a certain means, then there is a gap, and then the verse says: "one becomes Bhairava oneself" or uses a similar expression.

The Sanskrit text was published for the first time in 1918 in Bombay. A French translation and commentary by Lilian Silburn, the grande dame of Western scholarship on Kashmir Shaivism, appeared in 1961. The first English translation by Jaideva Singh was published in 1979, while a German translation by Bettina Bäumer came out in 2003. All three authors have been disciples of Swami Lakshman Joo, up to now the last Kashmiri Shaiva master, and their translations and interpretations are based on his teaching. He has taught the text several times in his Ashram in Srinagar in different languages: Kashmiri, Hindi, and English. Therefore, it is interesting that now his own, authentic interpretation is available. The precision and depth of his commentary is impressive. The quality becomes even clearer if one compares it with the very general treatment and absolutely free translation of the text by Rajneesh in his "Book of Secrets." The main basis of the commentary of Swami Lakshman Joo, who was at the same time a mystic and scholar (pandita), is the immediacy of his own spiritual practice since childhood and his experience of all the dharanas. The famous secret language of the tantras makes the difficulties in understanding the text insurmountable. Therefore, the oral commentary tradition is indispensable, as Abhinavagupta says in one of his own commentaries: "One cannot say everything in a book."

The present edition is exemplary: It gives the Sanskrit text in Nagari script and transliteration, followed by the English translation and commentary. It is the fruit of years of work by Bettina Bäumer and Sarla Kumar (India), who have edited the transcription of recordings of his teaching of the text in English in the seventies.

For anyone who wants to deepen his or her spiritual path this book can be helpful because of the detailed explanation of the exercises or experiences. Its wide range—whether the exercises concern breath, emptiness, awareness in eating, running, or listening to music—makes it possible for everyone to find his or her individual approach.

The book is a contribution to a contemporary spirituality, which we are urgently looking for—beyond a refuge from the world or getting lost in the world. It offers a view of life that suspends the borders between the sacred and the profane, the separation between God and world, without being a mere pantheism. As Utpaladeva, the grand-teacher of Abhinavagupta, exclaims in his hymns: "On what site do you not dwell? What exists that does not exist in your body?" It represents a spirituality that doesn't neglect the universe, the body, sexuality, or the ordinary life of mortals (which is in fact so extraordinary), but discovers God with all and in all of it.
