Because the more an allopath grows old the less he believes in his medicines. In a trolley car, when you see two physicians, one an allopath and one a homeopath, you know what they think. One thinks of the leg of the patient which will be in the anatomy, pathological anatomy, whether it can be cut off to cure disease. If it is of the abdomen whether there is a tumour and so on. Well he thinks of negative. But the homoeopath is always smiling and thinking what remedy may I find for this patient, there may be a remedy for this patient may be we will be able to save this patient. Mostly he always he always thinks with hope there is always the possibility of learning something more. The more an allopath grows old, the more he is pessimistic the more the homoeopath grows old, the more he is enthusiastic and optimistic.
