When the great sage Nārada was chanting the glories of the Lord, the bluish line on the neck of Lord Śiva disappeared. Upon seeing this, Gaurī, the wife of Lord Śiva, suspected Lord Śiva of being someone else disguised as her husband, and out of fear she immediately left his company. Upon hearing the chanting of Kṛṣṇa’s name, Lord Balarāma saw that His dress had become white, although He was generally accustomed to a bluish dress. And the cowherd girls saw all of the water of the Yamunā River turn into milk, so they began to churn it into butter. In other words, by the spreading of Kṛṣṇa consciousness, or the glories of Kṛṣṇa, everything became white and pure.
