A nirmanakaya which actually, in flesh and blood, repeats in space and time is the only final logical result of the bodhisattva vow. And if this vow doesn't in fact, in reality span death, then it's just a symbol. And we might as well pick and choose whatever symbol de jour is in fashion. Self generate f******g Mickey Mouse who cares it's not strong enough to resist the amnesia of rebirth, just like the metaphorical vow of your guru.
When you receive authorization to self generate and complete the yidam, you're no longer a practitioner. You're not just nailed to a metaphor or symbol or simile. You're nailed to the flesh and blood guru, which means you're nailed to the lineage. You're a holder of that lineage. You're not just sitting on a cushion any more but a chair of office. And what are you going to say from that position of responsibility, well, I like this, I quibble with that, this is ok but of course that thing is dumb, etc? WTF. You don't choose to be nailed to the guru's this but not his that. You've bought the whole package soup to nuts. Otherwise you're just a joke from vajra hell like all the other fake shmucks.
And what are you going to say, my guru's vow is just some nice words we say when we start our practice but come on it's not like it's more powerful than death or anything. He couldn't actually, really come back like the vow says, that's just a metaphor. Oh yea? What is that you're sucking into your heart and huffing and puffing through your inner mandala, some metaphor that death could just snap it's fingers and make disappear? You might as well quit the yidam and start popping a balloon every day as your practice. What the hell I don't believe I even have to be explaining this, I don't even have a yidam you're the one who should be telling me this. Degenerate age, kali yuga, blah blah, if you're a lineage holder - who's responsible?!
Emptiness isn't some ultimate view get out of jail free card you hand to your guru to apologize for all the crap in relative view you don't like. The reverse. One flavor is mirror like wisdom, ok? The rising sun from the east, the MF vajra itself. What do you think that means? Every f*****g shmuck knows he's conscious. Ask anyone if they're conscious. Yes, conscious, check. Reflection of phenomena, check. That's ordinary, we know about that already. Consciousness, big deal. Conscious guru, big deal. Super mega consciousness guru, big deal. Guru who's ripped open the boundaries of consciousness and seen beyond the blah blah blah, snore, snore, big deal. We know about it. Snore. We could draw a cartoon of that kind of guru, Superman breaking open the doors of perception, yawn, whatever.
That isn't mirror like wisdom. Everyone thinks that a reflection is just "me". Yawn, there it is, again me. The cup of coffee me. The super mega guru who went up into dhatu ... dharmakaya ... thing ... whatever. The guru who climbed the groovy ladder into the vision of the blah blah blah of awesomeness, zzzzz. "Me". We get that guru already. it's the "me" guru. You might as well get your cup of coffee to tell you how groovy consciousness is.
The point of mirror like wisdom is that ok, sure it's "you". But also - it isn't you. point to the cup of coffee. Point to the reflection in the mirror. What do you expect the reflection to do feel what you're feeling see what you're seeing? It isn't you. Get it? There not just one reflection in the mirror there's the reflection which is obviously you and one which is obviously not-you-but-still-somehow-you. The whole point is that the reflection which is "you" is limited by every single thing that is part of nama rupa, like your beliefs about how cups of coffee have to be, about your parents. Including - the limitations resulting from the amnesia of death and rebirth. Why else is death and rebirth part of Mara' wheel? Every single thing whatsoever in the reflection-that-is-me is limited. Including by the limit of death.
So the point is, if in addition to the reflection-that-is-me there is also clearly and obviously a reflection-that-is-not-me - where in the living hell did that come from? It cannot come from me "me" by definition, by the "me" that is limited by anything, including anything that is limited by death or amnesia, or likewise from the "me" guru whose flesh and blood is likewise a cause for that guru to be limited by death and amnesia. It's not enough for guru to break on through. That's just another "me" idea, just another "me" reflection, just another cartoon. It's a Doors song. So your guru can break in through so what even Jim Morrison was super mega groovy conscious and could break on through.
The whole point of mirror like wisdom is that there is a part of the coffee cup and the guru and me which is completely and totally apart from any frame of reference or limitation whatsoever that I or the "me" guru have ever experienced or conceived. Including the frame of reference of this one, single life. What do you think, your guru clenched his teeth and held his breath and took a quick peek? Before he had to take a breath and come back to this one life where he remembers that coffee cups are coffee cups and everything works like it should work after he was born? That guru is completely within the frame of reference of how things work in this single life. Vajra guru doesn't have to clench his teeth and take a breath and take a quick peek, he is in it 24/7. If that's not your view of kundzop guru, if you're not breathing something that is beyond death and from another life beyond all frames of references in this life - give it up, go hand out packed lunches or something, you're not doing your yidam, you don't have an inner mandala, you're doing Mickey Mouse, and you're just inside a cartoon of something you already know about.
How can you possibly take refuge in that kind of vajra guru? A guru who just clenches his teeth because he's just lucky to learn some stuff about how to clench his teeth properly and realizes something groovy? We know all about clenching our teeth and realizing something groovy already. It's not that hard just take some LSD or whatever. We know all about visiting heaven and hell thank you very much we have lots of cartoons and ideas and BS about it already. That's the reflection of me. Yawn.
What we don't know, what will shock the living hell out of us, what we can't imagine or conceive, is something that is 110% not-me, something that comes from beyond this one life of the coffee cup, this one life of the guru, this one life of mine. It's where rubbing the coffee cup all over your body isn't just some weird perspective we can take a peek at, it's totally normal, because it's from someone else's normal someone else's life, another one of my lives. Vajra Guru doesn't just take a peek at that other life, he is that other life. Something from another life completely, not just as a metaphor, not just as a 50% not-me, but as a 100%, not-me, a thread, a continuity, a nature, a guru, from beyond all of this me, this frame of reference, this one rebirth, this amnesia, this entire aggregate of limitations in time and space. That's consciousness, that's the mirror like wisdom of consciousness.
