Hello George,
Yes, Osho does mention Gurdjieff in several of his videos and he thinks highly of Gurdjieff’s philosophy. I’ve had several inquiries about Grudjieff’s teachings through Osho’s admiration of Gurdjieff.

The cost is not something that is fixed. I find that those who can afford to pay are able to contribute more than others. You being a high school or a college student are able to contribute a limited amount.
Depending on the level of your desire for knowledge and growth must be taking prior to what it will cost. You may end up paying little or nothing depending on your financial circumstances. I do not turn serious students away and money is not the factor.
As your growth and understanding increases, in time, you’ll find a way to make room to contribute what you can.

I hope this answers your question, so, give send me an email with your Skype name and let me know the best time to call you and we’ll find out if we can work together to see if we are on the same path.
Lewis
