However, if Maharaji were now to be offering something which was only a benevolent experience...

Putting aside for the moment who and what Maharaji is, how can anyone 'offer an experience'? At least in the spiritual or feel-good sense that you mean it in.

People can make suggestions as to how I might have a particular experience ('take this substance', 'sit like this and chant this', 'stand like that and think of that'...etc). But they are not 'offering' an experience, only making suggestions as to how I might sit, stand or act so that I might create for myself a particular experience.

So I find in your question an assumption that I reject. The assumption is that there are other people who can somehow engender in me an experience in the sense you mean it. This is bordering on the spritual master idea, as someone whose grace/ideas/inspiration/presence I need in order to have this 'benevolent' experience.

That people can have good ideas as to what I might do, and that I can listen to their ideas, and think 'oh yes, I'll try that' is fine. But in that case I am not bestowing on them any 'spiritual master' status that seems to me to be implied by your use of the word 'offering'.

...without people having to mortgage up to the hilt, surrender their own judgement, and so on, would this be objectionable?

People hearing the Keys have very much to surrender their own judgement. That is why they have to listen to so many videos first, so that they will surrender their own judgement to be 'ready' for Knowledge. In fact, the definition of being 'ready for Knowledge' is that you have surrendered your own judgement.

Although Maharaji is now packaging his message differently, underneath it is still the same message: what we really need (to find our 'heart') can only be given ('offered') by someone like him who has inspiration (read 'Grace') to make it work in our lives. Without him and his Grace/inspiration we can go nowhere, and are doomed to live at the mercy of our 'mind'.

I reject this whole philosophy, and the belief-system that surrounds it, totally.
