George Harrison about TM Meditation in 1970

George Harrison appeared on TV on Fact or Fantasy in 1970 to talk about the benefits that TM meditation brought him (Transcription of the video) :

People always say I'm the beatles who changed the most, but really that's what I see life is about. 
The point is, unless you're God conscious, then you have to change, because it's a waste of time. 
Everybody is so limited and so really useless, when you think about the limitations on yourself. 
And the whole thing is to change, try and make everything better and better. 
And that's what the physical world is about, is change. 
But the change that happens through meditation, I mean, it's a gradual sort of thing. 
But the more you realize with anything, with just growing older, the more you realize it helps you in some way. With meditation, you're able to understand that there is this unity lying beneath everything, there's something there within every atom that holds it all together and then in actual fact it really is one.
But on an intellectual level to say it is "we are one", then I mean again you missed the point, it's an experience you have to really have that perception that it's one. Maharishi said, ‘For a forest to be green, each tree must be green.’
So if you stand back and criticize the rest of the people, it's again, Christ said, ‘Put your own house in order’.
Automatically, if I'm to criticize somebody else, I suddenly come back to myself and realize, until I'm straight, then I'm in no position to be able to criticize others. 
So it helps. 
Also, it helps in as much as you can, anytime of the day, any situation you're in, you can get control of yourself just by sitting quietly and by turning off from the external problems.
we have noise and all this society, that you can go inside yourself, where it's always calm and peaceful, it's like being on this level of consciousness, it's like the ocean, which is always changing, and the bottom of the ocean is always calm and still. 
And if you're not anchored to the bottom of the ocean, you're at the mercy of whatever change goes on. 
This process of meditation or different types of yoga is all just a way to anchor yourself securely to that pure state of consciousness to that state of being, so that you can still act out your life on the surface, but you remain anchored securely.
