Do you know who you are? I shall tell you. Hear me. You are the master of the body and the senses and the mind. You are the master of your life. All power is within you. You have to know this and manifest it.
How can the mind torment you? How can despair overcome you? Despair is a quality of the mind and the mind is your servant. You are all bliss, all light, all strength, all knowledge. You are divinity. You are above and beyond both body and mind. You are immortal - satchidananda (existence - knowledge - bliss absolute).
The important thing to know clearly is that you are not the slave of the mind and the senses. You have got into the habit of thinking that their craving is your craving. Now get out of this habit, by constantly reminding yourself that you have nothing to do with the mischievous mind and senses.
Remember constantly that you are not this perishable body. You are not this perishable, changing mind. You are the all-pervading consciousness. You are the eternal seer. You are the eternal witness. Therefore be ever free and blissful.
Intensify your spiritual life. Seek the light of vedanta. Be a flame of the light of the Upanishads. Ever meditate on: "I am the immortal, all-pervading Brahman." Om is the bow, the soul is the arrow and Brahman is the target.
When you realise the effulgent Supreme Being you shake off all evil and attain the supreme stainless unity. Devote yourself to the holy quest of truth. Devote yourself to the discovery of the ultimate spiritual essence that is all-pervading and interpenetrating.
Withdraw the senses. Look within and search your heart. Dive deep into the recesses of your heart, through deep meditation on the innermost self, the inner ruler. You will doubtless realise your identity with Brahman and get to the heart of the infinite - the heart of infinite joy and bliss.
