-Part 1 Here-
And if we turn inward and prove our True Nature, that True Self is no-self, our own self is no-self, we go beyond ego and past clever words. Then the gate to the oneness of cause-and-effect is thrown open. Not two and not three, straight ahead runs the Way. Our form now being no-form, in going and returning we never leave home. Our thought now being no-thought, our dancing and songs are the Voice of the Dharma. How vast is the heaven of boundless Samadhi! How bright and transparent the moonlight of wisdom! What is there outside us? What is there we lack?
-From the Song of Zazen
The Baha'i Faith is a mystical religion. Baha'u'llah describes the spiritual seeker in the Valley of Knowledge - "the last plane of limitation" - as one who has "passed over the worlds of names, and fled beyond the worlds of attributes as swift as lightning" and has "made their dwelling-place in the shadow of the Essence."
It is also a practical religion. Baha'u'llah emphasizes the need to be "anxiously concerned with the needs of the age ye live in, and centre your deliberations on its exigencies and requirements."
Putting these two things together requires being “in the world, but not of the world” so to speak. This requires a delicate balance and careful integration of the two modes; yet they are each distinct. They are mutually reinforcing but they also develop along different axis.
Somewhat along these lines, in Buddhism there are three types of training which reinforce and integrate with each other, yet are distinct: morality, concentration, and insight.
