People quite often forget the simplicity of the technique. Often I like to remind my students, that reaching the meditative state is as effortless as a mote of dust falling onto a rose petal. When one engages the mantra, the importance is not to try and manipulate your way into a meditative state by concentrating or controlling, but to effortlessly surrender yourself to the natural desire of the mind to find greater levels of charm. The mantra is the vehicle that provides this charm. Take it as it comes, be effortless.
