Gurudev, Why is it absolutely necessary to have a Guru in one's Life to realise the Self?

Question - Gurudev,

Why is it absolutely necessary to have a Guru in one's Life to realise the Self?

Gurudev @SriSriRaviShankar ji - Let me explain this by narrating a story. 10 people were going from one village to another. On the way they had to cross a river. After crossing they wanted to be sure all were there. Each one started counting but counted only nine. They were very distraught and began to cry for the loss of the tenth.

A wise man came along and asked them "Oh my dear friends, why are you crying?"

"We were ten but now we are only nine," they replied.

The wise man saw they were ten, so he asked them to count. Each counted nine but left out himself. Then the wise man made them stand and count, and he said to the last person, "You are the tenth!"

And they all rejoiced for having regained the tenth.

Similarly the five senses and the four inner faculties (mind, intellect, memory, ego) all lament when they lose sight of the Self. Then the Master comes and shows you that You are the tenth! Count, but never stop until you find the tenth. The joy is in finding the Ever Present.

With the knowledge of the Self inside everything is truly joyful.
