I vaguely remember interesting Sutta in which Buddha was asked about all the various ways his disciples are teaching Dhamma (I think Sariputta was one of the examples). The person wanted to know which way was correct. The Buddha replied - all these teachings are correct and added his own take (which included generic advice about going through the Jhanas, seeing signs of fabrication and if needed go higher up).
Please tell me I didn’t make this up!
