What is the most beneficial interaction?

That interaction that contributes to the stability of mind and eventually leads it to become still is the most beneficial interaction.

The presence of Mahatmas, Guru, or a guide is useful for this purpose. In Satsang the mind should become calm and peaceful.

Any other interaction that destabilizes the mind and makes it fluctuate is not useful for Self Realization.

In order to grasp this point, the mind must be ripe for teaching. Else more world experience is needed and after sufficient suffering the mind becomes ripe to cultivate dispassion and ready for spiritual instruction. The mind may cycle back and forth to the world before becoming rooted on the path.
