Meditation is in vogue and many seem to be interested in it as well as practising it. In these days of instant coffee, two minute noodles and jet-speed travel, people seek instant realisation through quick means, by instant meditation. But there is no short cut to meditation or realisation. Dhyanasvarupam composed and commented upon by Swami Tejomayananda in a very simple way first explains the 'principles of meditation' by negating what is not meditation and then asserting what it is. Thereafter the 'principle of the practice of mediation' is explained. This is a very popular book and is a basic text for any course on meditation. From the level of the novice, the sadhaka is guided to the heights of meditation in a language easily intelligible even to the layman.
