Spirituality has, for the most part, focused on a realization of the higher nature of existence, and this has led to something of a dichotomy or dual existence for the seeker. It is a common experience that the seeker goes into a status that brings about the realization of some aspect of the higher nature, but in order to do so, he must abandon the outer life which is either distracting or dilutive of that experience. And then, when the experience withdraws, the seeker is left with the unreformed lower nature reverting to its habitual modes of action.
Sri Aurobindo observes: “We have not to leave them separate so that we live a sort of double life, spiritual within or above, mental and material in our active and earthly living; we have to re-view and remould the lower living in the light, force and joy of the higher reality. We have to realise Matter as a sense-created mould of Spirit, a vehicle for all manifestation of the light, force and joy of Sachchidananda in the highest conditions of terrestrial being and activity. We have to see Life as a channel for the infinite Force divine and break the barrier of sense-created and mind-created farness and division from it so that that divine Power may take possession of and direct and change all our life-activities until our vitality transfigured ceases in the end to be the limited life-force which now supports mind and body and becomes a figure of the all-blissful conscious-force of Sachchidananda. We have similarly to change our sensational and emotional mentality into a play of the divine Love and universal Delight; and we have to surcharge the intellect which seeks to know and will in us with the light of the divine Knowledge-Will until it is transformed into a figure of that higher and sublime activity.”
