In plain words
It is only the body that has to do with diseases like these, not humanness. We must take up the holy spiritual path that recognises such humanness and lives by it.
We must not think that the spiritual means being alone or living a solitary life. The principle of the Ātma, which has nothing to do with attachment and hatred: that is what we must see rightly. The spiritual path is the path that makes all mankind one, a unity, and brings it to fulfilment wholly. It is not a matter of hymns and bhajans alone. These we may call good deeds. The spiritual principle is the principle that shapes all mankind into one and into wholeness. In it we must all think of ourselves as children of one mother. Just as a child longs to reach its mother, so all men must make the fitting effort to reach the Mother who is God. When a closed flower blossoms, it pours out its fragrance and sweetness all around. At first it is only a bud. In the same way, the bud of our humanness, lying in a state of mere Ajñāna, has no chance at all of such blossoming. We must make the effort to bring this bud to ripeness. One who has learnt to swim pays no heed to the depth of the water and gives it no thought. With easy, splashing strokes he reaches the far bank. In the same way, if we understand the divinity that is God's own nature, we will give no thought to the troubles or the cares of this sea of saṃsāra.
When a bird has perched on the branch of a tree and that branch sways in the wind, the bird does not tremble or take fright at all. Why? It relies on its own wings, not on the branch. But man today, without even the faith of that little bird, trembling and quaking at any small trouble that comes in worldly life. He does not rely on his own self-confidence. So every man must develop self-confidence.
One hates the other. This envy is a very wicked thing. Only because of this envy do people suffer over one another, at the sight of another's good, another's greatness, another's joy. It is the chief of all the vices. This envy is not good for man. That is why in the Bhagavad Gītā He said, ‘Be one without envy.’ Then, in many forms too, there is belief and unbelief. What is this unbelief? Is it unbelief merely to say there is no God? No. No. It lies in its very name. My ‘is’ has turned into ‘is not’. If we were to say it in English, we would say ‘There is no God’. ‘There is’ came first. ‘no God’ came after. Is this a fancy? Is it true? If we think there is no God at all, who then is there? You? Who are you? If you understand your own true nature, you will be blessed in truth. So whoever sets out to offer the path of Satya with Prema, forbearance and calm, giving no way at all within his humanness to anger, hatred and envy, that man's life becomes blessed.
