The man of science knows, in one aspect, that the world is not merely what it appears to be to our senses; he knows that earth and water are really the play of forces that manifest themselves to us as earth and water--how, we can but partially apprehend. Likewise the man who has his spiritual eyes open knows that the ultimate truth about earth and water lies in our apprehension of the eternal will which works in time and takes shape in the forces we realise under those aspects. This is not mere knowledge, as science is, but it is a preception 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 the union of kindred things. The man whose acquaintance with the world does not lead him 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. When a man does not realise his kinship with the world, he lives in a prison-house whose walls are alien to him. When he meets the eternal spirit in all objects, then is he emancipated, for then he discovers the fullest significance of the world into which he is born; then he finds himself in perfect truth, and his harmony with the all is established. In India men are enjoined to be fully awake to the fact that they are in the closest relation to things around them, body and soul, and that they are to hail the morning sun, the flowing water, the fruitful earth, as the manifestation of the same living truth which holds them in its embrace. Thus the text of our everyday meditation is the _Gayathri_, a verse which is considered to be the epitome of all the Vedas. By its help we try to realise the essential unity of the world with the conscious soul of man; we learn to perceive the unity held together by the one Eternal Spirit, whose power creates the earth, the sky, and the stars, and at the same time irradiates our minds with the light of a consciousness that moves and exists in unbroken continuity with the outer world.
