The third eye is the gate that opens to the space of higher consciousness and to the inner worlds. It is also the main organ through which the spiritual energy can be awakened and regulated. The third eye (also known as the inner eye or the mind's eye) is a mystical concept referring to an invisible eye, which provides perception beyond the ordinary sight. The Third Eye is the seat of intuitive wisdom, of subtle information and spiritual or occult power. The third eye acts as a 'switch', which can stimulate the seeker to the transcendental state of consciousness. It is the spiritual laser for stimulating your inner awakening; it is the beacon that guides you to your true destination the long-awaited home you have been so passionately longing for. It is the lighthouse of consciousness, which the truth-seekers wish to rely upon. Each one of us possesses the 'Third Eye', but without the grace of the spiritual master (Guru) or without the suitable spiritual technique, the third eye remains underdeveloped. Conclusively it is the Dharma (duty) of every human on this planet to awaken or open his/her third eye during this lifespan itself in order to reap innumerable benefits in physical, mental, emotional, psychological, spiritual and astral planes. It is not only our dharma; it should be our right to avail the infinite blessings from God Almighty by opening our third eye. The current book is a sincere effort to introduce the topic of third eye to the readers along with the techniques of opening the third eye and the benefits accrued there from. Besides the extensive coverage on the well-known 'Third Eye of Lord Shiva' (in Hinduism), this book describes the third eye, its location, the technique of its awakening in other faiths and religions also, viz., Buddhism, Taoism, Jainism, Christianity, Kashmir Shaivism, Sufism, Sikhism, Gnosticism, the 'Eye of Horus', and the Eye of Ra etc. Thus this is a truly multi-religious and multi-faith book, which will definitely draw the attention of all the readers across the Globe interested in this important spiritual subject. Further, this book stepwise explains various techniques for opening one's third eye. The last chapter of this book lists many benefits accrued to those seekers whose third eye is either fully opened or in the process of awakening. All these aspects are comprehensively covered in the eighteen chapters, supported by 85 figures in this book. Approximately 35 number of original Sanskrit mantras (hymns), written in Devanagri as well as Roman scripts along with their meanings (in English) have been included in this book in order to give authenticity and scholasticism to this book. A sincere effort has been made to ensure that this book appeals equally well to the scholars, the seekers and the common people having a simple knowledge of English language and believing in the vast spiritual treasure hidden in their ancient scriptures.
