Step by step

But, let Me tell you that married life and being a grihastha (householder) will not bar your way to Realisation. Look upon the wife and the children as a sacred trust, and serve them in that spirit. Prepare yourselves for a celibate and spiritual discipline from the age of fifty; the five senses have to be mastered, by the time five decades of your life are over. The conclusion of six decades means that you. have conquered the six foes of man: lust, anger, greed, attachment, pride and hate. When you are seventy, you must have become ready to merge with the seven sages, the seven seas and the seven colours of the solar ray; that is to say, you must be far, far above mundane desires and ideals, and as near the point of mergence as possible, through sadhana. Eighty must see you in line with the deities that preside over the eight cardinal points, more or less Divine, in attributes and characteristics. Ninety takes you, or rather should take you to the realm of the Nine Planets, into the realm of the Super. When man reaches the hundred mark, living out the ten decades, he must have mastered the ten senses, the five senses of action and the five senses of knowledge and become Wisdom incarnate, with no trace of action or the consequence thereof or the desire for it. He and the Absolute are One and Indivisible!
