Why do the Siddhas not reveal themselves so easily?
Basically, the Siddha system is not a philosophical school, but is a school of Mystics. It is a path of energy and power. It is like playing with sword, if we are not attuned to it, it may harm. If the Siddhas do come forward to the people all of us would approach them in a materialistic way, with an acquiring tendency to gain power. Or we would have an attitude of spiritual materialism. They hide themselves because there is already a strong conditioning about them and their ability for Siddhis. But, even if we do see a Siddha, walking along the roadside, we would never recognise him for he would make himself extremely unapproachable by behaving like a dirty, mad or eccentric person. Our very first approach to Him would shatter our conditioning His only message being to shed more and more and more of the acquired.
