With Sandaka 53.4

53.4

Na ca nāma sadhammokkaṃsanā bhavissati, na paradhammavambhanā, āyatane ca dhammadesanā tāva bahukā ca niyyātāro paññāyissanti.

Namely, that there’s no glorifying one’s own teaching and putting down the teaching of others. The Dhamma is taught in its own field, and so many emancipated are recognized.
