Another thing—it is a mistake to argue from one’s own very limited experience, ignoring that of others, and build on it large generalisations about Yoga. This is what many do, but the method has obvious demerits. You have no experience of major realisations through work, and you conclude that such realisations are impossible. But what of the many who have had them—elsewhere and here too in the Asram? That has no value? You kindly hint to me that I have failed to get anything by works? How do you know? I have not written the history of my sadhana—if I had, you would have seen that if I had not made action and work one of my chief means of realisation—well, there would have been no sadhana and no realisation except that, perhaps, of Nirvana.
