The practice of Yantras in Nidrâ Yoga

Forms and Colors of the Being

Nidrā Yoga (yoga of dream and conscious sleep) is rooted in the traditions of Kashmir Shaivism and Vedanta, both dating back several thousand years. It presents the organization of the human being through five layers (koshas) to discover, explore, and intimately understand how to establish oneself in a state of consciousness where there exists no trace of separation, conflict, or suffering.

Nidrā Yoga is a practice towards complete lucidity, a journey from oblivion to self-presence. It is a gradual approach to awareness and to the sensation of being completely live. Very paradoxically, this awareness can only be perceived in a deep state of surrendering.

During the practice we consciously relax the muscles, organs, bones, sense organs (eyes, ears…), the process of sensing (vision, hearing…), and the various functions of the mind to transcend the limited self and to come into the field of cosmic consciousness when time, space and the Ego all dissolve, and there is nothing left but the experience of oneness. It is very psychologically purifying. The normal ups and downs of life begin to affect us less and less as we attain a joyful equanimity. Aside from relaxation, Nidrā yoga also involves concentration practices to find the balance between relaxation and concentration to trigger this super-conscious state.

Forms and colours

A little known aspect of Nidrā Yoga addresses the inner path through Yantras

The yoga of forms and colours leads to the steps of concentration and meditation codified by Patanjali.

This yoga uses simple geometric shapes and primary colours that are first visualised in the practice of Nidrā Yoga then reproduced on paper before finally being used for contemplation, revealing hidden dimensions of being.

In a second stage, they are combined into more complex geometric shapes (yantras) to provide a real opening to the pure meditative state (without object) which is described as samadhi or the natural state of being


During 3 weekends online we study the effects of geometric shapes on the state of the mind through the practice of Nidrā, discovering the world of simple shapes (square, circle, triangle, point) and their use in altering one’s state of mind.

The colours also have a big role and add another layer to the drawn shapes. These workshops bring us back to our childhood state of joy and playfulness.

The winter week (January 2022) in Latvia (or/and online) is a research on more complex Yantras and one’s own personal Yantra, which remains a support and a meditation tool for life.

This program of three weekends and one winter week is a complete module to address this yogic path in its entirety. The program is taught in English.

The teacher

André Riehl lived in a Himalayan monastery before spending several years in a spiritual quest in India among masters and instructors of diverse traditions. He had the opportunity to deepen his spiritual practice with Kashmiri Babu, an ascetic monk in the Shivaite tradition. He was profoundly touched by his contact with Jiddu Krishnamurti and Sri Ma Ananda Mayee. Being a disciple of Chandra Swami in the Brahmanic lineage of the Udasins allowed him to integrate all the previous teachings. In 1972, André became the president of the Federation of Traditional Yoga (France). Certified teacher in NIDRĀ YOGA by the Federation of Traditional Yoga; European Union of Yoga and the National Yoga Confederation of India.

Desiring to participate in the transmission and the preserving of the yogic culture, he dedicates himself to transmitting authentic teachings combining ancestral knowledge with contemporary attitudes through courses and seminars. From this point of view, the teaching which André offers combines an ensemble of practices allowing to integrate diverse facets which form our identity and our way of being in the world: development of the breath and conscious respiration, studies of the levels of relaxation and lucid dreaming, awakening the intuition, development of the degrees of concentration, using and mastering the faculties of sense, Sanskrit chanting, interior silence, and study of traditional texts.
