This Mahāyāna Buddhist sūtra has been especially influential in the Chn school of Chinese Buddhism. Some of the key themes of the Śūraṅgama Sūtra form the foundation for Buddhist practice, mainly by samādhi power. The moral precepts in this Sutra are so important that they are often used to combat delusions that may arise during meditation. This book serves as a guide for all Buddhist practitioners to understand the basic ideas of Buddhism and lead their hands through the way of factual practice toward the ten stages of Mahāyāna achievements.
