If we meet even one true spiritual Guru during our lifetime, I believe that we will get answers to all the questions of life. It is like a boat wandering in the sea finding a shore.
I have met many spiritual sages and mahatmas while roaming in the Indian Himalayas. I remember once a Guru made me aware of the taste of food, after which food does not attract me so much till date.
In Banaras I met a Guru who said that if I don't do this, people will not leave me alone. That Guru used to abuse the greedy people who came to him so that people would consider him greedy and would not come to him again.
Walk with awareness because it is not necessary that a Guru will be wearing a robe, who knows someone may come in pants and shirt and open all the closed doors of life and go away. I am remembering the words of Gautam Buddha "अप्प दीपो भव:"
