1. The Mother: Individual, Universal, Transcendent
If it is the same part of the vital that was on the right side and has now turned against the Mother, the explanation is very obvious. It gave its adhesion formerly because it thought that by its adhesion it could make her satisfy its desires; finding its desires not indulged, it turns against her. That is the usual vital movement in ordinary man and in ordinary life, and it has no true place in Yoga. It was just the introduction of this attitude into Yoga by the sadhaks and its persistence which has at last made it necessary for the Mother to draw back as she has done. What you have to do is to get these lower parts to understand 
that they exist not for themselves but for the Divine and to give their adhesion, without claim or arrière-pensée or subterfuge. It is the whole issue at the present moment in the sadhana; for it is only if this is done that the physical consciousness can change and become fit for the descent. Otherwise there will always be these ups and downs in some part of the being at least, delay, confusion and disorder. This is the only true basis for fixity in the true consciousness and for a smooth course in the sadhana.
