In plain words
The mountains do not put on any rug because it is cold. They do not go to a hill Station because the sun is too hot. They do not switch on any airconditioning. Nor, deluded over how to bear the rains, do they hold up any umbrellas. The mountains, which have recognised the Satya that cold, sun and rain are for the body alone, and the Ātma has none of them, have been teaching man in many ways. This is the second Guru.
"Do not fret over tomorrow and the evening after," the birds teach the lesson of contentment.
When they feel hungry, the birds go to some place or other then and there, fill their stomachs, and lead their lives happily, comfortably and peacefully. But they do not draw up this 5 year plan for tomorrow and the evening after, and go through endless toil for food and drink. For human life there is no certainty at all of tomorrow or the evening after. Who knows what tomorrow will bring? What Satya is there that we will stay here till tomorrow? For a life like a bubble on the water we scramble in many ways for tomorrow and the evening after, and so waste this span of life. The birds too have been teaching us in many ways that this is not the divinity that befits humanity.
"The body is not eternal, worldly life is an illusion," say those who leave the body and depart.
How many die before our very eyes! How many are born! How many leave us and go! We do not try to recognise this. However much he sees, however much he hears, however much he experiences, man still does not give up this delusion about the body. So it is vital to slip, step by step, somewhat out of our obligation to the principle of the body. "The delusion of 'mine' and 'I' is unworthy": what is ours? What is our land? What is our possession? What is our principle? Without enquiring into this, we keep saying of everything "mine" and "I", and for selfish ends and our own gain we let time and the body slip into neglect in many ways. The very principle of Nature has been teaching us this well. The spring that has passed comes round again. The many seasons come back again. Even the waning moon shines again. But the world itself teaches us that the water of a river and the youth of a man never come back.
The Guru. Who is our true Guru? Is not divine Nature, which gives us such an inner teaching, our true Guru? This very universe is our Guru.
