Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 14

Sanskrit:

नाधिगच्छेत् स्त्रियं प्राज्ञ: कर्हिचिन्मृत्युमात्मन: ।बलाधिकै: स हन्येत गजैरन्यैर्गजो यथा ॥ १४ ॥

ITRANS:

nādhigacchet striyaṁ prājñaḥkarhicin mṛtyum ātmanaḥbalādhikaiḥ sa hanyetagajair anyair gajo yathā

Translation:

A man possessing intelligent discrimination should not under any circumstances try to exploit the beautiful form of a woman for his sense gratification. Just as an elephant trying to enjoy a she-elephant is killed by other bull elephants also enjoying her company, one trying to enjoy a lady’s company can at any moment be killed by her other lovers who are stronger than he.

Purport:

Just as one is enchanted by the beautiful form of a woman, many other men will also be enchanted, and there is danger that they will be stronger than oneself and may even jealously kill one. Crimes of passion are extremely common. This is another disadvantage of material life.
