Shree Krishna now declares the consequence of properly preaching the message of the Bhagavad Gita. He says such preachers first attain his para bhakti, and then attain him.

The opportunity to engage ourselves in devotion is a special blessing of God, but the opportunity to help others engage in devotion is an even bigger blessing, which attracts the special grace of God. Whenever we share something good with others, we benefit from it too. When we share whatever knowledge we have with others, by grace our own knowledge increases as well. By often giving food to others, we never go hungry ourselves. Saint Kabir said:

dāna diye dhana nā ghaṭe, nadī ghate na nīra

apane hātha dekha lo, yoṅ kyā kahe kabīra [v42]

“Wealth does not decrease by giving in charity; a river does not become narrow, though people take water from it. I am not saying this without basis; see it yourself in the world.” Thus, those who share the spiritual knowledge of the Bhagavad Gita with others receive the highest blessing themselves.
