user-1: With many traditions and teachers to choose from, how should one go about figuring out what is the true Dhamma?
I prefer answers based on Buddhist scriptute and references to Sutta, ideally to the Buddha himself.
I welcome answers from all traditions just not opinion based.

"Of course you are uncertain, Kalamas. Of course you are in doubt. When there are reasons for doubt, uncertainty is born. So in this case, Kalamas, don't go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, 'This contemplative is our teacher.' When you know for yourselves that, 'These qualities are unskillful; these qualities are blameworthy; these qualities are criticized by the wise; these qualities, when adopted & carried out, lead to harm & to suffering' — then you should abandon them.

So he said to the Blessed One, "Master Gotama, with regard to the ancient hymns of the brahmans — passed down through oral transmission & included in their canon — the brahmans have come to the definite conclusion that "Only this is true; anything else is worthless." What does Master Gotama have to say to this?"

With many traditions and teachers to choose from, how should one figure out what is the true Dhamma?

From AN 8.53

"Gotami, the qualities of which you may know, 'These qualities lead to passion, not to dispassion; to being fettered, not to being unfettered; to accumulating, not to shedding; to self-aggrandizement, not to modesty; to discontent, not to contentment; to entanglement, not to seclusion; to laziness, not to aroused persistence; to being burdensome, not to being unburdensome': You may categorically hold, 'This is not the Dhamma, this is not the Vinaya, this is not the Teacher's instruction.'


"As for the qualities of which you may know, 'These qualities lead to dispassion, not to passion; to being unfettered, not to being fettered; to shedding, not to accumulating; to modesty, not to self-aggrandizement; to contentment, not to discontent; to seclusion, not to entanglement; to aroused persistence, not to laziness; to being unburdensome, not to being burdensome': You may categorically hold, 'This is the Dhamma, this is the Vinaya, this is the Teacher's instruction.'"
