We live in an age of lemming like mass hysteria, so nothing new there then! Except modern media and social media technologies make the effect almost instantaneous. People follow without thinking and understanding. On our path of transcendence what we must do is think and understand, resisting the peer pressure to follow blindly. Without understanding there is ignorance and ignorance is ultimately destructive.
Personal evolution and transcendence requires an understanding of our individuality and its place in relation to the world and indeed the cosmos. We are but one pixel in the picture of creation, we must look wider to see the whole picture for that will bring understanding and that in turn will bring transcendence.
