Hello Aniduan,
I don’t think Sotapannas (or any others with certain magga phala) have similar capabilities for explaining dhamma concepts to others.
– Understanding and explaining are two different things.
For example, a Sammasambuddha (like Buddha Gotama) discovers Buddha Dhamma on his own and can also explain it to others.
– On the other hand, a paccekabuddha discovers Buddha Dhamma on his own but CANNOT explain it to others.
