I found a few poems of Rabindranath Tagore in my notes. They express very beautifully the vision filled of wonder of the person who is awake to the presence of the Lord in his life, in nature and in himself.
These poems give us precious clues on how to integrate and assimilate the teaching of the Upanishads about Isvara, the Lord, in our lives. It is thus enabling us to be aware of the presence of a Being, to which I, the world and all human beings are fundamentally ‘connected’ to or in which all is ‘united’.
Because in reality, there is only one Being who is, and who is manifest as the multiple forms of the universe, and who is including me as an individual. All these forms are always changing within this all intelligence and power, and are never separated from Him at any time.
To understand this vision completely, what we have heard from the teaching has to percolate in the depth of ourselves, go much beyond a superficial understanding of the concepts of material-intelligent cause or manifest-unmanifest, maya, etc. The presence of Isvara can indeed become a reality, a fact we are alive to. There is no place for imagination here, nor a blind assent to a system of beliefs. But rather a slow personal work, a process of unveiling, a relation with Isvara which grows patiently and leads to a silent inner revolution, with appreciation of the presence of His grace with us all along.
This particular type of poetry is a real bridge which enables us to see the presence of Isvara in everything and in our life, when it is allied with a proper teaching. More I think about it, more I believe that it is impossible to bypass Isvara if one wants to gain serenity, joy and ultimately freedom.
The same stream of life that runs through my veins night and day
runs through the world and dances in rhythmic measures.
It is the same life that shoots in joy through the dust of the earth
in numberless blades of grass
and breaks into tumultuous waves of leaves and flowers.
It is the same life that is rocked in the ocean-cradle of birth
and of death, in ebb and in flow.
I feel my limbs are made glorious by the touch of this world of life.
And my pride is from the life-throb of ages dancing in my blood this moment..’
Light, my light, the world-filling light,
the eye-kissing light,
Ah, the light dances, my darling, at the center of my life; the light strikes, my darling, the chords of my love;
the sky opens, the wind runs wild, laughter passes over the earth.
The butterflies spread their sails on the sea of light.
Lilies and jasmines surge up on the crest of the waves of light.
The light is shattered into gold on every cloud, my darling, and it scatters gems in profusion.
Mirth spreads from leaf to leaf, my darling,
and gladness without measure.
The heaven’s river has drowned its banks
and the flood of joy is abroad..
