Background

Training rule Bi Sk 39 belongs to the Sekhiya group (Training Rules — Sikkhāpada) within the section of the Vinaya devoted specifically to Bhikkhunīs. The Sekhiya rules are a collection of training rules concerning conduct, deportment, and manner of behaviour in daily life, especially during the reception and consumption of meals. These are training rules of proper bearing (ācāra) and discipline (vinaya); they do not fall into the category of grave offences such as Pārājika or Saṅghādisesa, yet they play an important role in forming the character of the practitioner and in establishing the confidence of lay supporters.

In the Pāli Canon, the Sekhiya system typically comprises numerous clauses arranged by thematic groups, among which a significant cluster concerns the manner of taking meals. Bi Sk 39 carries the Pāli keyword Nātimahanta — meaning "not [making] overlarge" — evoking the principle of moderation and mindfulness in each movement by which food is brought to the mouth.

Content Determinable from the Descriptive Information

The title and the Pāli keyword Nātimahanta allow the essential content of this training rule to be clearly identified: the prohibition against making an overlarge mouthful when taking a meal. The prefix na- in Pāli carries a negative meaning ("not"), while atimahanta means "too large," "too big," or "beyond the ordinary measure." The full expression Nātimahanta may therefore be understood as the rule: "One must not form a mouthful that exceeds the appropriate size."

The specific behaviour regulated is the manner in which a practitioner takes up food and places it in the mouth. If the morsel of food that is taken or formed is too large, this manifests a lack of mindfulness and self-restraint, and may give rise to several unwholesome consequences: it may affect one's deportment before those who are making an offering, it may produce ungraceful sounds during chewing, or it may even cause physical discomfort. This is one of the training rules that Vinaya scholars refer to as rules concerning the manner of eating (bhojanasikkhāpada).

The prefix Bi (an abbreviation of Bhikkhunī) confirms that this training rule belongs to the Bhikkhunī Pātimokkha, that is, the body of Vinaya rules for women who have gone forth in the Theravāda tradition. Nevertheless, the Sekhiya rules concerning eating and drinking generally run parallel to or correspond with the Sekhiya rules in the Bhikkhu Pātimokkha, reflecting the common principle of decorum for monastics of both orders.

Significance for Practice

The training rule against making an overlarge mouthful, though it may appear minor in form, contains a profound meaning for practice within the Theravāda Buddhist tradition.

First, it is an expression of mindfulness in daily life (sati). The practitioner is reminded that every action, however small, must be carried out in full awareness. To bring a mouthful of food to the mouth with care and in the proper measure is precisely to practise mindfulness in each moment of one's life.

Second, this training rule embodies the principle of moderation (mattaññutā) — knowing sufficiency, knowing the appropriate measure. Theravāda Buddhism lays particular emphasis on the quality of contentment (santosa) and restraint (saṃvara) in every domain, including eating and drinking. A mouthful taken in the fitting measure is not merely a gesture of courtesy, but also a manifestation of an inwardly well-cultivated mind.

Third, decorum in taking meals is of great importance for the relationship between the Sangha and society. When lay people observe a bhikkhunī receiving her meal with dignified composure, this gives rise to confidence and veneration, and contributes to the maintenance of society's support for the Sangha. The Sekhiya rules are therefore not merely individual precepts but also a means of establishing the Jewel of the Sangha (Saṅgharatana) in the eyes of the world.

Fourth, considered in the deeper dimension of meditation, the regulation of each small behaviour — such as the size of a mouthful — is an indispensable exercise for developing concentration (samādhi) and wisdom (paññā). One who cannot restrain oneself in small matters will find it difficult to maintain restraint in greater spiritual challenges.
