Row, row, row your boat gently down the stream. Merrily, merrily, merrily, merrily, life is but a dream. Dream images appear real, but they are not. Ordinary appearances to our eyes, ears, etc. appear real, but they are not. The next time you get upset, think, “Who is this ‘me’ who is upset? Where is such an ‘I?’ Can you precisely locate it? This kind of reflection can dissolve feelings of being upset, etc. Be persistent trying this again and again.
