There are many paths to enlightenment, self-realization, and higher levels of consciousness. There are paths like devotion and a discriminating mind. The wisdom traditions are clear that the path of meditation is the fastest and most effective.
To quote my guru, “You are impatient and expect to attain heaven all at once. You cannot get it by reading books or by listening to sermons or by doing charitable works. You can get it only by giving your time to Him in deep meditation.”
He also says, “Meditation is that special form of concentration in which the attention has been liberated from restlessness and is focused on God. Meditation, therefore, is concentration used to know God.”
