When someone has decided to consecrate his life to the seeking for the Divine, if he is sincere, that is to say, if the resolution is sincere and carried out sincerely, there is absolutely nothing to fear, because all that happens or will happen to him will lead him by the shortest way to this realisation.
That is the response of the Grace. People believe that the Grace means making everything smooth for all your life. It is not true. The Grace works for the realisation of your aspiration and everything is arranged to gain the most prompt, the quickest realisation – so there is nothing to fear. Fear comes with insincerity. If you want a comfortable life, agreeable circumstances, etc., you are putting conditions and restrictions, and then you can fear. But it has no business in the sadhana!
