The notion of dhammamātā is one of the last items of the legacy of the late Buddhadāsa Bhikkhu. In order to accord women practitioners better social status and provide them with opportunities for spiritual training, Buddhadāsa avoided committing himself to the reintroduction of bhikkunī ordination. Instead, he proposed the notion of dhammamātā, which literally means ‘dhamma mother’. This article postulates that by using the metaphor of the mother, Buddhadāsa invited less conflict, appealing to the high respect which Thai people generally held for women. Moreover, the article argues that with dhammamātā Buddhadāsa challenged the common notion of motherhood which usually regards women as nurturers of the Sanġha. Dhammamātā nurture people's spirituality through their teaching and virtues. Whilst the social impact of dhammamātā cannot be compared to that of bhikkunī, whose yellow robes visually suggest a status equivalent to that of male bhikkhu, the concept of dhammamātā was a new creation revolving around the image of the female religious teacher, a role that Buddhist women had wanted.
