MENTOR - capitalised - a friend of Odysseus entrusted with the education of Odysseus' son Telemachus (http://www.merriam-webster.com/dictionary/mentor).
In Hindi the word gets translated to संरक्षक (sanrakshak) though I like परामर्शदाता (paramarshdata) more. These words have been used in Indian mythology repeatedly. Which just goes on to show that Indian society had an excellent model for anyone seeking guidance since time immemorial.
I find traces of such actions today. If someone becomes successful, s/he is too busy creating more success for self than being able to mentor someone else to gain success. Has our society become too self-centered or egoistic?
