It is fruitless to see and talk of the material modes of nature and their resultant so-called happiness and distress as if they were factual. When the mind wanders during the day and a man begins to think himself extremely important, or when he dreams at night and sees a beautiful woman enjoying with him, these are merely false dreams. Similarly, the happiness and distress caused by the material senses should be understood to be meaningless.
