Bhagavad Gita Verse 16.8

वे आसुरी प्रकृति वाले मनुष्य कहा करते हैं कि जगत् आश्रयरहित, सर्वथा असत्य और बिना ईश्वर के, अपने आप केवल स्त्री-पुरुष के संयोग से उत्पन्न है, अतएव केवल काम ही इसका कारण है । इसके सिवा और क्या है ? ।

Men of this evil nature generally say that this world has no truth; is without a basis for morality and good-will; that no Lord exists and that nobody should show any love or devotion to Him; that there is no regular sequence (or law) of creation; and that birth is only the result of a natural union (of man and woman) and comes about due to pure lust and nothing else.
