I spent most of this past weekend involved in an amusing but intense conflict with an apprentice. It matters little to me. I have all the time in the world. Most don't.
The problem with attempting to teach is that most who call themselves apprentices or even just seekers appear to wholeheartedly believe they are already Masters of the Universe, Keepers of All Knowledge, and Resident Experts on Everything In Existence. The mere fact that the reality of it is a trifle different never occurs to them, and they will spend most of their time arguing for what they often say is their "right to be heard" (*banging fist on the table and expanding chest like a puffer fish*)
My hearing is excellent. My experience is comparatively vast when held up next to that of most 18-30 year olds who initially say they want to learn from me, but then create entire little armies of dissenters who do nothing but argue and attempt to discredit the messenger. If that's your goal, it's fairly easy to do. After all, this messenger has claimed to be immortal, so he has given you all the ammunition you should need to bury his credibility in a shiny mahogany coffin somewhere in the vicinity of Forest Lawn. It isn't necessary to endlessly debate my teachings. It is only necessary that - if you really want to learn - you try them and be willing to move on if you find they don't work for you, or even if they don't resonate with your existing programming to such an extent that you are filled with angst and dread at the mere thought of continuing on this path I have described.
Do what works for you. But don't assume that when something doesn't work for you, it's the fault of the teaching or even the teacher. Most times, apprentices fail not because the teachings are flawed, but because the apprentice insists on remaining flawed even when being offered a long list of workable solutions. I'm not speaking only of my own teachings, but any teachings of any competent spiritual adviser.
It must also be taken into account that words do not exist to adequately explain much of what occurs within the apprentice during this process of bootstrap evolution. It reminds me of the oft-repeated statement that only when you are on the far side of the bridge do you have the capacity to look over your shoulder to see how the bridge was built. Change is difficult on a good day, and virtually impossible on a bad day. Some might say most days are bad days, but my perspective is that most days are insignificantly neutral. Life is what you make of it. If you Intend to attain the immortal condition, nothing can stop you. If you're looking for reasons to say it's impossible, you've already lost the battle (and yourself).
Define what you want. Know who you are and don't pretend to be someone you aren't. If you are being someone you aren't, where is that going to lead you? Are you trying to emulate the change you want to embody, or are you just being a poser while you wait for Death to come calling?
If you aren't doing whatever it is you do out of a sense of love and wonder, you are running in place on a slippery slope. You can't waste my time. But you can definitely waste your own. Think about it.
