Meditation is a stand-alone discipline, but I integrate it within a yoga class, after the asana and pranayama. Meditation calms the mind, clears the clutter and sharpens thinking. It also brings about many AHA! moments, revealing sought-after answers to pressing questions.
Contrary to religious fears about meditation, it does not worhip a god or involve religious rites or rituals. Meditation is simply the process of taming the mind. It is often said that the mind is a formidable enemy. What happens then when you tame the mind? You gain a powerful ally.
My meditation background is Vipassana - a silent 10-day meditation course (I do not teach Vipassana meditation as only a certified Vipassana teacher can do so). I've done 7 courses, interspersed between sitting as a meditator and serving the sitting meditators. The experience is nothing less than transformative. This is the reason why I include meditation as part of my yoga class.
