Rabindranath Tagore explores some of the most found question of life as he reveals the meaning of spiritual practice. 'The man who has his spiritual eyes open knows that the ultimate truth about earth and water lies in the apprehension of the eternal will which works in time and takes shape in the forces we realize under those aspects. This is not mere knowledge, as science is, but it is a perception of the soul by the soul. This does not lead us to power, as knowledge does, but it gives us joy, which is the product of kindred things. The man whose acquaintance with the world does not lead deeper than science leads him, will never understand what it is that the man with the spiritual vision finds in these natural phenomena. The water does not merely cleanse his limbs, but it purifies his heart; for it touches his soul. The earth does not merely hold his body, but it gladdens his mind; for its contact is more than a physical contact, -it is a living presence.”
