When a plane flies across the sky, it leaves no mark on it, no streak that lasts, no furrow or pothole that interferes with further traffic. So too, allow all feelings and emotions to cross your mind, but do not allow them to cause an impression. This can be done by inquiry, by quiet reasoning within oneself, more than listening to lectures or study of books. Little children are trained to walk by means of a three-wheeled contraption which they hold and push along. The Pranava is such a contraption, with the three wheels of A, U and M – the ‘Omkara Tricycle’. Holding it, you can learn to use the two feet of Bhakti and Vairagya (devotion and detachment). When you give up your hold on the Omkara, you slump down on the floor helplessly. When you walk everyday reciting the Pranava,you will definitely realise the glory of the Divine, which is the very substance of the Universe.
