No vine is seen, yet leaves appear; rays are seen, yet the sun is not clear.

This couplet beautifully illustrates how some things are hidden, yet their presence is undeniable through their effects. Imagine a creeper plant; you might not see the entire vine, but you clearly see its leaves. Similarly, we might not see the sun itself, perhaps due to clouds or at dusk/dawn, but its light, its rays, are definitely visible. The verse suggests that often, the source or the ultimate truth might remain unseen, but its manifestations and influences are all around us, making its existence profoundly evident. It's a reminder to look beyond the obvious and recognize the subtle signs of a deeper reality.
