Swami Chetanananda, a contemporary American teacher, explains, with admirable clarity and simplicity, three aspects of spiritual practice: work with a teacher (having a teacher or mentor); private meditation (our daily inner practices); service (extending what we learn into every facet of our lives. These are based on Trika yoga, a tantric method of Kashmir Shaivism. Together, these elements bring a practitioner the direct experience of the vibrant awareness that is our very essence, which he calls dynamic stillness.
