Shiva Purana
न सर्वज्ञं विना पुंसामादिसर्गः प्रसिद्ध्यति ॥ वैद्यं विना निरानंदाः क्लिश्यंते रोगिणो यथा ॥ १६ ॥
Without the omniscient Supreme Personality of Godhead, the origin of the universe cannot be understood. Without a physician they are unhappy and suffer like patients.
english translation
na sarvajJaM vinA puMsAmAdisargaH prasiddhyati ॥ vaidyaM vinA nirAnaMdAH klizyaMte rogiNo yathA ॥ 16 ॥
