Repetition of the Divine Name is the simplest path to dispel the lower forces from your mind. Naama, or Mantra are most powerful for they have been chanted from timeless time. Guru says keep doing japa with love and surrender, the rest is His grace and natural unfoldment of the flow life soaked in light.  Don’t worry about the future; just let your mind do japa mantra ceaselessly. His Grace is boundless.
