Intuitively I have been finding Nisargaddata Maharaj and the way he teaches Advaita Vedanta very inspiring. Recently I discovered why. This is a supreme way to describe the so called "Oneness Consciousness" that we all talk about related with the end of the Mayan calendar. Also depending on my experience of practicing different spiritual paths for many years (Vipassana, Sufism, Tantra, different Yogic paths...) I would say that Advaita Vedanta is pretty much of a direct path. Well, you might say Vipassana or Tantra would also be direct ways.
