Dharana Darshan is a practical and informative text on the yogic, tantric and upanishadic practices of concentration and visualization, as taught by Swami Niranjanananda Saraswati. These practices, which traditionally have never been taught except through direct transmission from guru to disciple, represent an advanced level of teaching and are intended to meet a need expressed by many serious practitioners for more guidance into the deeper dimensions of meditation. The book includes an introduction to the theory of dharana and detailed class transcripts of the techniques.
