It's funny, because Mahayana argument of their "superiority" towards Theravada by "Skillful Means" , shows that actualy is not Mahayana that is "superior" school, but Theravada.
Because some beings have just to see anicca dukkha and anatta, just some ethical rules and simple meditative technics to get free,
and others need much more complicated explications and methods
Truth is simple, more something is simple, less it is conditioned, and so less dukkha and anicca
Lie is complicated, more something is complicated, more it's complex, more it is conditioned, and so more dukkha and anicca
If we watch closely what The Blessed One said to "The Elders" (SN 22.83-93), like Ananda sutta, Tissa sutta, Yamaka sutta, Vekkali sutta... what we see? We see that, if i rememer, all of these Elders are Arahants, and Buddha said them some very simple Dhamma, what is this Dhamma? Just that fenomena are anicca, dukkha and anatta, that they are conditioned, thats all.
Some knots are simple, some knots are complicated. I feel compassion to these last ones.
Sabbe dhamma anatta
We are not concurents...
