A child one day came to its guardian very perplexed because a boy had said to it, "Do you believe in Santa Claus? If you do then it is not right, because there never was such a being as Santa Claus." This child was very disappointed, because it had just written a letter to Santa Claus before Christmas. And in its great despair it came to the guardian to ask, "Is it true that Santa Claus exists, or is it not true?" Now suppose the guardian had said, "It is true", then in four or five years" time the child would have come and said, "No, it is not true"; and if he had said, "No, it is not true", then all the child's belief would have been totally destroyed. It would have been completely changed if the guardian had said, "It is not true." That would have rooted out, just by saying no, all the innocent religious belief from the heart of that child. But the guardian said to it, "Remember, all that the mind can conceive exists. If it does not exist on the physical plane, it exists in the sphere of mind. So never say it does not exist. To the one who says that it does not exist, say that it exists in the sphere of mind"; and the child was very impressed by this answer.
