Because teaching is being available ... An old man came to a saint to ask him about the mysteries of life and generously the holy man shared his wisdom. Pleased the old man went to his cell but as soon as he closed the door he realised he had forgotten what the holy man had said to him. He looked for him again and once more the saint answered his questions but as soon as he returned to his cell he realised that he had forgotten everything again. After some other attempts, ashamed he said to the holy man: - I easily forget everything you teach me and now I donâ€™t dare to ask you anymore. Night was coming down beyond the small windows of the monastery and so the saint said to the old man: - Go for a lamp and come back to me. The old man did what he asked and came back with a burning lamp. - Please, use that one to light the other lamps in the room, as it is getting dark â€“ asked the saint. Again, the old man did it as told and soon all the lamps in the room were burning. - Did the lamp you used to light the others suffer something because of it? Did it loose its strength and its light? Is it less shining now after helping all the others to start burning? - No â€“ Said the old man. - So do not hesitate each time you want to ask me something. I will answer you again and again.
