The clouds are symbols of obscurity.
The vision you had was of the mental plane and symbolic. It symbolised not so much your own position as the general difficulties which lie in the way of one's going deep inside into the psychic centre and living there. The maidan (field) full of light was the inmost psychic centre; the dark place in between represents the veil of ignorance created by the gulf between this inmost psychic and the outer nature. The chakra turning round and round which prevents the approach from one side (the mental side) is the activity of the ordinary mind; when the mind becomes quiet, then it is easier. The serpent is the vital energy which covers up the psychic and prevents approach from another (the vital) side. There again if the vital becomes quiet, then the approach is easier.
The blows in the forehead were perhaps the working of a force to open the centre there -- for there between the eyes is the centre of the inner mind, will and vision. All these centres are closed in the ordinary consciousness or else only very slightly open in the surface. If the inner mind centre opens, then the peace, etc. from above can enter easily into the mind and afterwards into the vital and both mind and vital will become quiet.
Our life's uncertain way winds circling on,
Our mind's unquiet search asks always light,
Till they have learnt their secret in their source,
In the light of the Timeless and its Spaceless home,
In the joy of the Eternal sole and one.
But now the Light supreme is far away:
Our conscious life obeys the inconscience' laws;
To ignorant purposes and blind desires
Our hearts are moved by an ambiguous force;
Even our mind's conquests wear a battered crown.
