Having been advised, Dhruva started his meditation, and went without food and water for six months, his mind fixed on the Lord. The austerity of his tapasya shook the heavens and the Lord appeared before him, but the child would not open his eyes because he was still merged in his inner vision of Vishnu's form described to him by Narada. Lord Vishnu had to adopt a strategy of causing that inner vision to disappear. Immediately Dhruva opened his eyes, and, seeing outside what he had been seeing all along in his mental vision, prostrated himself before the Lord. But he could not utter a single word. The Lord touched his right cheek by his divine conch and that sparked off his speech. Out poured forth a beautiful poem of praise of the Lord in 12 powerful verses, which together are called Dhruva-stuti.
