You may have noticed the "Subway Mantras" recently. In spite of the book being very short (probably 10 minutes cover to cover), it is really a workbook, and it may take some time to truly appreciate the power of the ancient technology that it presents. It was not a frivolous project as it took almost ten years. It all started when I sheepishly said to my teacher Shree Vinayak, while doing yoga, "I wish I could read Sanskrit", to which he replied: "Very easi, I teach you". That, he did.
