Thanks to Shiv, Jayanti, Paritosh and to Tom for the very pertinent replies to my inquiry. I feel my question to be more than answered and I will be pondering these points. I especially think that the "inner security" as mentioned by Jayanti hits the very bottom of the well. It is when fear comes that my security leaves me and it is only when I am calm that I remember Mother. I will try to keep the sweet and beautiful face of Swamiji in my mind as it seems to calm me.
