Sit comfortably and quieten your mind. Visualise the image of Mother Mary in your mind's eye.
See her energetic Blue Cloak in your mind's eye.
Call on Her presence. 'Oh Divine Mother, please come to me; bless me with your Presence and reveal yourself'. You may become aware of a colour, a sensation or a strong rush of emotion. Allow, allow, allow. You may want to stay in the awareness of her Grace for a few moments before continueing.
