On earth their is day and night. But in the sun all is light.Similarly in the world you experience day of pleasure and the night of pain .This cycle goes on succeeding the other. All your lifetime you go through the joys and sorrows of the world. But the source of these experience in life is the inner sun in you. That sun is your own soul. Your all-blissful Self. That is your original source. That is your ultimate goal of life. You must realise this truth. If you do not you are like the ignorant masses who experience day and night without realising that the sun above is responsible for it.
The object and goal of life is that every human being should realise the divinity within himself. You should realise your unity with God. You should utilise your worldly ties and experiences to realise your oneness with your supreme Self. That is consummation of Human existence. There is nothing that remains to be desired when you reach that goal. Thereafter no physical beauties, no emotional ecstasies, no intellectual reveries can distract your attention. You are in supreme joy,perfect bliss. That bliss transcends all language and surpasses all description. That infinite happiness is the nature of your own Self. Oh, what a blunder you commit, what an error in giving up this supreme bliss for worldly shadows of pleasures, for mere will-o' -the-wisp. You have sold your birthright like Esau for a mess of pottage. Judas Iscariot sold Christ for thirty pieces of silver. You too have done so with your Christ within. You should be wiser than that. The sweet nectar of divinity lies within you. Seek it in you own Self. It is not in your body or mind or intellect; it is not in desires or objects of desires - It transcends all this. It is your Self within.In the Kena Upanishad the preceptor deplores the state of man who has given up his real Self for the sake of the world. Woe unto him who doesnot realise his real nature here in this world.
"If one has realised one's Self here, truth is fulfilled; if one does not realise one's Self here, it is supremely great loss. Reflecting upon the Self in every experience the wise transcend this world and attain immortality (Self)".
