Shiva is called as "Bholenath"-The one who is easily pleased. Although some, take the meaning literally, but I feel that there is something deeper and philosophical meaning to this word.

What other meaning for this word my small mind has understood is:
Bholenath, means
Bhole- child like people
nath- refuge, lord
So Shiva is lord of pure/childlike people. Or It may mean Lord who is childlike and purity himself.

Can someone elaborate this word into deeper meaning.
