I simply followed (my teacher's) instruction which was to focus the mind on pure being 'I am', and stay in it. I used to sit for hours together, with nothing but the 'I am' in my mind and soon peace and joy and a deep all-embracing love became my normal state. In it all disappeared -- myself, my Guru, the life I lived, the world around me. Only peace remained and unfathomable silence.
