The demands of work, family, or school can overwhelm even the most dedicated yogi. If you are in need of a spiritual tune-up, you may want to check out the "Inner Engineering" program offered by the Isha Foundation. Inner Engineering is "a modern antidote to stress, and presents simple but powerful processes from yogic science to purify the system and increase health and inner well being. Program components include guided meditations and transmission of the sacred Shambhavi Maha Mudra. When practiced on a regular basis, these tools have the potential to enhance one's experience of life on many levels." For more information, call 650-575-5827, email sfo@ishafoundation.org, or visit www.ishafoundation.org. The program is next being offered in Milpitas, Calif., August 13-19. It costs $290 but you can check it out for free on August 13 at 7pm at the Indian Community Center on Los Coches Road. Has anyone out there ever experienced "Inner Engineering?"
