Openness is not always complete from the first―a part of the being opens, other parts of the consciousness remain still closed or half open only―one has to aspire till all is open. Even with the best and most powerful Sadhaks the full opening takes time; nor is there anyone who has been able to abandon everything at once without any struggle. There is no reason to feel therefore that if you call you will not be heard―the Mother knows the difficulties of human nature and will help you through. Persevere always, call always and then after each difficulty there will be a progress.
