I believe Krishnaprem’s comment was on a passage in which I wrote that this Yoga was not like the old ones in that it aimed not at an ascent or passing beyond life but at a descent of the divine consciousness into life. Its aim is double – two movements fusing themselves into one – an ascending into divine consciousness and a transformation of earth life by the divine consciousness coming down here. All the old Yogas put the emphasis on going to Nirvana or to heaven, Vaikuntha, Goloka, Brahmaloka, etc. for good and so getting rid of rebirth. My emphasis is on life here and its transformation and I put that as the aim at once of my Yoga and of the terrestrial manifestation. I am quite unaware that any of the old Yogas held this as the aim before them. Even Vaishnavism and Tantra are in the end otherworldly: mukti is the aim of their efforts and anything else could be only coincidental and subordinate or a result on the way. If my view is correct, then my statement was not an error.
I have not denied that the ideal of a change on earth is of old standing. It is there vaguely in the human mind perhaps since the beginning, though more often perfection is put in some golden age of the past and deterioration and a cataclysm 
is the law of the future. Christianity foresees a descent of Christ and his rule on earth, but this is figured as a natural event, not as a change produced by an inward power and process or by Yoga. A reign of the saints is also foreshadowed in some Hindu scriptures, but that equally is something different from my conception. As for sainthood itself or the siddhis of Yoga including a siddha body, that too is not what I mean by transformation, it is a radical change of consciousness and nature itself that I envisage. I do not know also that these things were sought by the process of descent – the Tamil Shaiva saints for instance sought for the siddha body by tremendous austerities; the siddhis they sought were all there in the sūkṣma mental and vital worlds and by a stupendous effort and mastery of the body they brought them down into the physical instrument. I have always said that these things and these methods are out of my scope and eschewed by me in my Yoga. I tried one of these but after achieving some initial results I saw it was a bypath and I left it.
To get rid of or mastery over kama-krodha [desire and anger] is not the transformation, it is at best a preliminary step towards it provided it is done not in the moral way by mental self control but in the spiritual way. Sainthood is not my object. I do not know how far Ramakrishna had gone towards the transformation as I conceive it; the metaphors you quote contain nothing precise with which I can compare my own experience or my own intuitions about the change. According to certain accounts there was a descent of Kali into his body which made it luminous, but he repressed it as something contrary to what he was seeking after. If there is something anywhere in the past which coincides with the aim and conceived process of my Yoga I shall be glad to know of it; for that would certainly be an aid to me. I put no value on the newness of what I am doing or trying to do. If the path was already there open and complete, it is a great pity that I should have wasted all my life cleaving it out anew with much difficulty and peril when I could just have walked on a clear and safe avenue towards the goal of my endeavour. But the 
nearest I could get to it were some things in the Veda and Upanishads (sacred words, veiled hints) which seemed to coincide with or point towards certain things in my own knowledge and experience. But after incorporating certain parts of the Vedic method as far as I could interpret or recover it, I found it was insufficient and I had to seek farther. [incomplete]
