This aspiration is perhaps point of this most difficult to understand and, I admit, that it took me sometime to don’t to my own understanding. You see, the inspiration for this training rule comes directly from the lojong slogan to “Drive all blames into one.”
As far as I have been able to understand this injunction it seems to mean that you take the blame for any situation upon yourself and free the other party from your own blame and animosity. This happens on an internal level so there is no worry regarding the 4th Precept. When it comes to responding to blame things become slightly more complicated.
A Dhamma friend on dhammawheel.com pointed out that to vernal accept blame for something you did not do would be tantamount to lying. Of course he is right and it wouldn’t make sense to break the precepts in an effort to walk the path. So what could this aspiration mean here?
To me it would mean surrender and non-contention. If someone is blaming you for the loss of their ring and you know that you had nothing to do with it you could simply tell them you’re sorry it is lost, that you have no idea where it is and that you’ll help them find it. If they go further and demand that you buy a new one you can take it on yourself as an act of charity to do so. Extreme? Maybe but they’re is something thrilling and invigorating about aspiring to mine by such principles.
