True happiness cannot be found in things that change and pass away. Pleasure and pain alternate inexorably. Happiness comes from the self and can be found in the self only. Find your real self (swarupa) and all else will come with it.
If you want peace and harmony in the world, you must have peace and harmony in your hearts and minds.
Once you reject what you are not, whatever finally remains, the leftover, is yourself – your true nature. Presently, whatever you know is ‘I am’, this ‘I am’ is the product of the five elements. Out of the elements comes the food body and because of the food body, that ‘I amness’ is sustained. And you are also not that ‘I am’. ‘I am’ is the taste, the fragrance of this food body. The ultimate ‘you’ has no fragrance, no taste, no touch of ‘I amness’.
That state in which you were before you acquired this knowledge ‘I am’ is the real state. Only after you got this knowledge you identified with the body-mind. Whatever you have acquired, including the body-mind, that will go, and it is useless, and that is that. But your original state, before you acquired the body, is the Truth, is the Real state, and it will remain.
