A life without spiritual sadhana is a dreary waste. A life with spiritual sadhana is wise living — a life that will lead to Blessedness. The combination, the blending together, the harmonizing, the combining of an active inner spiritual life with an active outer secular life, fulfilling of the spiritual with the secular, the Divine with the earthly was Gurudev's special mission. And to that end he gave us one aspect of his teachings in the form of 20 Important Spiritual Instructions. These instructions comprise a harmonising of the outer and the inner, the emphasizing of the inner practising of the teachings of the ancient sages and seers of the Upanishads, practising of the teachings. This practise, together with the normal life is Gurudev's special teaching to the world, and the summing up, the practical 20 Important Special Instructions give us the key to Blessedness even while living in the world and through the world itself.
