मा पमायए भिक्खू, इत्थिसु संगमाचरे। ॥४.१॥
The monk should not be negligent — he should not practice attachment toward women.
Mahavira opens Chapter 4 by addressing monks directly and personally — "the monk should not be negligent." The word "negligence" (pamaya) in Jain practice carries real weight. It is not mere carelessness about minor details; it is the allowing of the mind to drift into channels of craving without noticing, without checking, without correcting. In the Jain understanding, negligence is perhaps the greatest practical danger on the path — more than willful wrongdoing, because negligence doesn't even register as a problem until it has already taken root. Attachment to women is introduced here as the primary and most powerful example of the kind of deep, persistent, habitual craving that the monk must be most vigilant against. This chapter is not primarily a moral statement about women — it is an extended training in the specific kind of vigilance required to face the strongest forms of sensory craving. Whatever your most powerful pull is, whatever form attachment takes in your own practice — this chapter is your chapter. The teacher is showing the monk the exact shape of the most dangerous obstacle and training him to see it coming before it arrives.
The simple version: The monk must stay alert. The strongest form of attachment is also the most dangerous threat to practice.
