Naga sadhu's in Maha kumbh

I have been watching maha kumbh in news and I see Lakhs of naga sadhu's living happily with just ash on them chanting Har Har mahadev. Here I am with a job, comfortable life but still some fell underachieved, Anxious and always in fear.

Telugu lo cheppali ante, Lord shiva ni talchukunt, aa smoke chesthu, almost no cloths tho happy ga untaru, I know spiritual oki deep ga velthe ella avthundi anne, but still comfortable life unna edho okka low feeling.
