Ascetics and fakirs come to mitigate human suffering to heal us and lead us on the path. They put up with criticism they go through many worldly trials. Some of them have even become martyrs for our sake. But they have done all this with a smile and with gratitude to God. Hence sacrifice is a great virtue.
We are not weak if we make a proper use of those means which the God of Nature has placed in our power... the battle sir is not to the strong alone it is to the vigilant the active the brave.
