The doctor first diagnoses the disease and then prescribes the course of treatment. So too, you must submit yourself to the diagnosis of your illness, viz. misery, travail, and pain through Self-Enquiry. Investigate fearlessly and with care, and you will find that your nature is bliss(ananda)! You have falsely identified yourself with the temporary, the frivolous and the paltry, and that attachment brings sorrow. Realise that both joy and sorrow are passing phases, like clouds across the blue sky. Learn to treat prosperity and adversity with equanimity. Just as fish lives only when it is immersed in water, so too human being lives only when immersed in bliss. You must have bliss at home, in society, and in the world, but more than all, in your heart. Your heart is the spring of joy. That spring must be touched by constant recitation of Lord's Name and dwelling on His Glory. Never give way to doubt or despair.
