Now comes the other side. Whoever takes this supreme secret — the knowledge of the Gita — and shares it among those who are ready, among Krishna's devotees, that person performs the highest act of devotion. And the result? They will come to Krishna. No doubt about it.
Teaching is itself a form of bhakti. When a person sits down with others and shares what the Gita says — not for fame, not for authority, but because the knowledge is precious and deserves to reach those who will honor it — that act is a form of worship. The lamp that lights another lamp does not lose its own flame.
The word 'asamshayah' — without doubt — closes the statement with absolute certainty. Krishna places no conditions on this promise beyond the act of sincere sharing among devotees.
