From Kailas's silvery cave-side, O northern winds, arise!

This beautiful couplet is a poetic call to the northern winds. It imagines these winds as sleeping peacefully in the "silvery lap" of Kailash's caves. "Silvery" could refer to the snow, moonlight, or just the ethereal beauty of the sacred mountain. The poet is gently rousing them, urging them to awaken and begin their journey. It evokes a sense of vastness, purity, and the majestic power of nature, originating from a revered, spiritual place like Mount Kailash. It's a vivid image of nature's awakening, full of grace and mystique.
