It should be understood that in those days I possessed no clairvoyant faculty, nor had I ever regarded myself as at all sensitive. 
I remember that I had a conviction that a man must be born with some psychic powers and with a sensitive body before he could do anything in the way of that kind of development, so that I had never thought of progress of that sort as possible for me in this incarnation, but had some hope that if I worked as well as I knew how in this life I might be born next time with vehicles more suitable to that particular line of advancement.

One day, however, when the Master Kuthumi honoured me with a visit, He asked me whether I had ever attempted a certain kind of mediation connected with the development of the mysterious power called Kundalini

I had of course heard of that power, but knew very little about it, and at any rate supposed it to be absolutely out of reach for Western people. However, He recommended me to make a few efforts along certain lines, which He pledged me not to divulge to anyone else except with His direct authorization, and told me that He would Himself watch over those efforts to see that no danger should ensue.

Naturally I took the hint, and worked away steadily, and I think I may say intensely, at that particular kind of meditation day after day. 

I must admit that it was very hard work and sometimes distinctly painful, but of course I persevered, and in due course began to achieve the results that I had been led to expect. 

Certain channels had to be opened and certain partitions broken down; I was told that forty days was a fair estimate of the average time required if the effort was really energetic and persevering. 

I worked at it for forty-two days, and seemed to myself to be on the brink of the final victory, when the Master Himself intervened and performed the final act of breaking through which completed the process, and enabled me thereafter to use astral sight while still retaining full consciousness in the physical body – which is equivalent to saying that the astral consciousness and memory became continuous whether the physical body was awake or asleep.

I was given to understand that my own effort would have enabled me to break through in twenty-four hours longer, but that the Master interfered because He wished to employ me at once in a certain piece of work.
