Fear...

"A wise man was asked by an inquirer, 'Why am I afraid?' Replied
the wise man, 'Because you have fixed notions.' The inquirer then
asked, 'Why do I have fixed notions?' to which his teacher replied,
'Because you are afraid.' When our frozen minds melt in the warm
light of understanding, there is a mental flowing in which there is
no fear."
