As the Upanishads say:
“Self is everywhere, shining forth out of all beings, vaster than the vast, subtler than the most subtle, unreachable, yet nearer that breath, that heartbeat. Eye can not see it, ear cannot hear it nor tongue utter it; only in deep absorption can the mind, grown pure and silent, merge with the formless truth. He who finds it is free; he has found himself; he has solved the great riddle; his heart forever is at peace. Whole, he enters the Whole. His personal self returns to its radiant, intimate, deathless source. As rivers lose name and form when they disappear into the sea, the sage leaves behind all traces when he disappears into the light. Perceiving the truth, he becomes the truth; he passes beyond all suffering, beyond death; all the knots of his heart are loosed.” (The Enlightened Heart, p. 4)
For a spiritual person, for someone who is on a spiritual path – purpose becomes his life, every minute, every action of one’s life has it’s purpose, it is the purpose. Purpose of this moment, of this task that one is facing at this moment – is that particular moment, and that particular task. It is all about staying present. That’s not easy, but it is a heck of a spiritual practice.
On the other hand, when you completely identified with your ego – and to me, this is the opposite of being present, awakened, spiritual – when ego rules your life, then your spirituality is also ego driven. Where your believes are better, righted, more spiritual that mine. Your life’s purpose is also something you are constantly looking for, searching, waiting to be revealed. Or, you think you know your purpose in life, and you keep working toward it, as if it’s full realization was somewhere in your future. This moment is nothing more to you, than means to an end, the stepping stone to something better, bigger.
The more present you are, the more you practice to accept each moment as is, you realize that if you treat each moment as a gift, there will be so many more gifts uncovering themselves to you.
