First of all, I would like to tell about the meaning of the word: ‘Guru’. Because this word has been very much changed in the world and people generally do not understand the true meaning. There are two words in it: ‘Gu’ and ‘Ru’. ‘Gu’ means, in Hindi and Sanskrit: darkness; ‘Ru’ means light. So a person who can lead the disciple out of his mental state of darkness, or ignorance and take him to the light – is known as ‘Guru’.
Soul – Atman – is dwelling in our body, in the form of energy, which itself, is enlightened. Weapons cannot cut it, nor can fire burn it, water can’t wet it, nor can wind dry it. This is a message from the Bhagavad Gita. Because Atman, the soul, is very fine, we cannot see it with our external eyes. If we want to see Soul, then we need inner eyes. And we need someone to show us the way. A person who has realised the Soul is known as Guru. So there are two things you need to know: there is a physical Guru, and there is spiritual. Physical is one thing, but spiritual is another thing – (it) is within you.
