Bhagavad Gita 4.2

Krishna speaks of a sacred lineage—the knowledge of yoga passed from saintly kings through unbroken tradition, now lost to the world through time's erosion of spiritual culture. This is not mere history; it is the lament of any age when living wisdom becomes myth, when practices become forgotten, when the bridge between heaven and earth grows invisible.

Yet hear this: the knowledge is never truly lost—only dormant in your own heart, waiting for sincerity to awaken it. When you turn inward with genuine longing, you become part of that eternal chain again.
