Firstly of course the intricacies of karmic effects cannot be known as even the Buddha did not elaborate and said that the effects are one of the 4 imponderable concepts that could drive one mad.
So I am pretty much looking for opinions here not what effects my actions will create.
Buddha once said that teaching what is not the Buddhas teaching as if it is Buddhas teachings creates heavy negative karma for us all and causes the true Dharma to disappear (my own interpretation)
What I am asking is that is paying for "buddhist" teachings (which to me paying is not dana and the spirit of Buddhism) and specifically paying for teachings that are said to be Buddhas teachings but are mixed with teachings that are NOT the Buddhas teachings, is this a negative karmic action?
My reasoning is that I have been asked to listen to some Mahayana teachings that I already know mix teachings that are not the Buddhas teachings, and I have been asked to pay for them as well.
From my side I want to listen to the teachings for the benefit of the person (a Mahyanaist nun) who wants me to listen to them, and in turn so we can discuss them, but I also do NOT want to contribute even in the slightest to the dissolving of the Dharma. In so I feel paying for these teachings contributes towards the dilution these Mahayana Buddhists may be doing.
This is not a Mahayana vs Theravada question that is not viable on this site for questions, I have explained the scenario for elaboration on my question.
This is simply a question about Sila from Theravada view point and specifically the above quote form the AN nikaya.
Thanks in advance
