CHĀNDOGYA UPANISHAD · 2.4.2
न हाप्सु प्रैत्य् अप्सुमान् भवति य एतद् एवं विद्वान् सर्वास्व् अप्सु पञ्चविधं सामोपास्ते ॥
na hāpsu praity apsumān bhavati ya etad evaṃ vidvān sarvāsv apsu pañcavidhaṃ sāmopāste ॥
He does not die in water, nay, he is rich in water who knowing this meditates on the fivefold Sâman as all waters.
F. Max Müller · The Upanishads, Sacred Books of the East 1 (1879)
