Rosemary, I am rushing off to Bourne End (Vedanta Centre) for a three day retreat to be conducted by Swami Veetamohananda of France and will be back on Thursday. Hence a brief comment.
Neither rejoice nor doubt but a simple trust in the Divine Mother's assurance is enough. Feelings of fear under your circumstances are normal. Every time such feeling comes, simply pray: "Divine Mother, what I call 'my son', really belongs to you. So please take good care of him and keep him safe. I as his earthly mother am simply his caretaker on your behalf." As a caretaker mother keep sending him your thoughts of love, everytime you think of him.
Vriju,
I know you are not "at home" now, but I must go ahead and deeply thank you for your reply. My mind is very strained and your words are most helpful.
