This is a monumental treatise that guides us on a profound and revelatory journey into the ancestral roots of shamanism. The book explores fundamental concepts of indigenous philosophy, such as communication with spirits, the power of sacred plants, and the psychic and energetic connection between species and humans, planet Earth and the cosmos. Throughout its pages, Artese presents a variety of terms and symbols related to these traditions, from 'Kahunas' to 'Nirvana', displaying a rich, synthetic and diverse vision of shamanic beliefs that extend throughout the world. A central theme in the book is the notion of 'Cosmic Consciousness', the state of mind expansion that can be achieved through these ceremonies, meditation and the use of power plants. This book explores how these practices can lead us to a deeper understanding of ourselves and divinity. Throughout the book, the author shares his own personal experiences and encounters with shamans from various cultures, as well as the teachings he received from them related to psychological aspects such as 'the shadow', which represents the elements of our personality that we reject, and the importance of initiation and purification rituals. This is a great invitation to reconnect with nature and to honor it as a place of power and wisdom, reminding us of the importance of living in harmony with our ecosystem. With an eloquent and lucid style, Léo Artese - one of the most influential shamanic leaders worldwide - takes us into the realm of the magical and the sacred toward understanding a higher human reality that we are unaware of.
