Letters of Sri Aurobindo
Volume III - Part 1
You forget that for a long time she was often keeping much more to herself, to X’s great anger. During that time she built up an inner life and made some attempt to change certain things in her outer – not in the outward appearance but in the movements governing it. There is still an enormous amount to be done before 
the inward change can be outwardly visible, but still she is not insincere in her resolution. As for her not having any depression it is because she has established a fundamental calm which is only upset by clashes with X; all the rest passes on the surface ruffling it perhaps, but not breaking the calm. She has also a day or two ago had the experience of the ascent above and of the wideness of peace and joy of the Infinite (free from the bodily sense and limitation) as also the descent down to the Muladhara. She does not know the names or technicalities of these things but her description which was minute and full of details was unmistakable. There are three or four others who have had this experience recently so that we may suppose the working of the Force is not altogether in vain, as this experience is a very big affair and is supposed to be, if stabilised, the summit of the old Yogas. For us it is only a beginning of spiritual transformation. I have said this though it is personal so that you may understand that outside defects and obstacles in the nature or the appearance of unyogicness does not necessarily mean that a person can do or is doing no sadhana.
