One other thought about the ocean comes from the Twelfth Canto of the Śrīmad-Bhāgavatam (SB 12.13.2) When the Supreme Personality of Godhead appeared as Lord Kūrma, a tortoise, His back was scratched by the sharp-edged stones lying on massive, whirling Mount Mandara, and this scratching made the Lord sleepy. May you all be protected by the winds caused by the Lord’s breathing in this sleepy condition. Ever since that time, even up to the present day, the ocean tides have imitated the Lord’s inhalation and exhalation by piously coming in and going out.
