"Where the mind is without fear and the head held high;
Where knowledge is free;"--
Tagore dreams about a socio-spiritual utopia where there is a fearless human spirit of boldness and a strong sense of self-respect for all human beings. The freedom of knowledge is a liberal ambiance, an anti-colonial strain can be heard here. what Tagore seems to oppose here is the hegemonic power of knowledge as tapped by the Ideological State Apparatus.
"Where the world has not been broken up into fragments by narrow domestic walls;
Where words come out from the depth of truth;"--
This is the imagination of a unified, peaceful and healthy world where there are no class/race/moral fragmentation and meanness. He also aspires for a spiritual honesty in linguistic representation and an unproblematic relation between the word and the world.
"Where tireless striving stretches its arms towards perfection;
Where the clear stream of reason has not lost its way into the dreary desert sand of dead habit;"---
In the imagined utopia, there would be an endless perfectionist journey in terms of cultural and social development. There would be revolutionary potential and a tendency towards new ideas in this world. It will not be dominated by 'dead habit' of conformity. The revolution would be backed by clear logic.
"Where the mind is led forward by Thee into ever-widening thought and action;
Into that heaven of freedom, my Father, let my country awake."---
There would be harmony in between thought and action in that world of honesty and the mind will strive towards a spiritual union with the divine spirit. The poem ends with an invocation to the divine father to uplift the existing reality to this paradise of liberty. The indication is clearly towards an independence from British bondage as far as India is concerned.
