Mother,
Yesterday during evening meditation I felt a pressure on the head which made my thoughts still and this was repeated once more when along with calm I experienced a sense of release as if something heavy and obstructing has been removed.
This means that the lid above is being removed and the Higher Consciousness is pressing on the lower – its first touch being that of silence and peace.
Last night I got up at about 2. And after walking a little in the bright moonlight outside the room in the verandah I tried to sleep again with a strong aspiration for the rising of the consciousness (or Kundalini). I must have slept some time but when I awoke I felt the rising sensation mildly, but by letting the body remain passive and willing for its continuation the rising in greater and greater force and height continued for more than half a dozen times. At that time my consciousness was wide awake and I prayed that I may surrender myself completely to You, Mother.
The whole consciousness was turned towards the process of rising as in a series of waves that pushed the being upwards and the body seemed like an empty lifeless chest.
But I cannot yet make the experience repeat while sitting up. Perhaps the absorption and relaxation that are necessary I have not learnt yet. In sleep while the outer being is relaxed Your Force works up the necessary conditions when alone the rising of the Kundalini is possible, which the Tantriks and Yogis of other schools do consciously after a laborious process of breath-regulation etc. Now I feel by your Grace much joy and ease in this experience and its recurrence also has increased but up to now this has not led to any further development.
With deep devotion
Prithwisingh
Nothing needs to be done to bring the ascension – aspiration is sufficient. The object of the ascension is for the lower nature to join the higher consciousness so that 
(1) the limit or lid between the higher and the lower maybe broken and disappear (2) the consciousness may have free access to higher and higher planes (3) a free way may be made for the descent of the higher Consciousness into the lower planes.
