Hòa Hảo presents itself as a reformist and distilled form of Buddhism oriented toward ordinary life. Adherents frame the movement’s core teaching as a return to the essentials: faith in the Buddha’s compassion, ethical living in the household, and simple daily recitation and remembrance rather than elaborate temple rites. The tradition’s own literature and oral accounts emphasize humility, filial piety, the duties of husband and wife, and the ethical responsibilities of neighbors — teachings attributed to the founder and preserved in vernacular collections of his sermons. These sermons and sayings, transmitted orally and in small printed tracts, became especially prominent in the Mekong Delta from the late 1930s and 1940s, when Hòa Hảo emerged as a distinct movement in the rural districts of what is today An Giang province and spread to adjacent provinces such as Cần Thơ, Kiên Giang, Sóc Trăng, and Bạc Liêu.
At the level of cosmology, Hòa Hảo uses familiar Buddhist vocabulary but often without the metaphysical elaboration of scholastic Mahāyāna systems. Adherents speak of karmic consequence, moral causation, and the possibility of spiritual progress through right conduct and recollection of the Buddha. Where Mahāyāna temple Buddhism in Vietnam has a rich iconography, liturgical calendar, and monastic corpus centered in urban pagodas and historic centers such as Huế or Saigon’s major temples, Hòa Hảo tends to foreground ethical practice in daily life and a personal, inward relationship to the Buddha. Scholars note this produces a distinct doctrinal contrast: whereas institutional Mahāyāna often emphasizes monastic learning, textual study, and the performance of ritual competence, Hòa Hảo emphasizes immediate moral reform by laypeople and household-based devotion.
A central concept in Hòa Hảo thought is the primacy of sincerity (thành tâm) and straightforward ethical reform. Adherents stress that outward ritual without inner rectitude is ineffectual; the tradition’s sermons repeatedly instruct followers to be honest, faithful to family, and to avoid gambling, opium, and moral laxity — concrete social prescriptions addressing everyday behavior. These injunctions connect Hòa Hảo to a broader strand of Buddhist ethics that privileges right livelihood and moral discipline as the route to personal and communal well‑being. In practice, this ethical focus is visible in common devotional practices: many households maintain a modest shrine with incense and short recitations, observe daily moral rules, and prefer vernacular prayers over lengthy liturgies. Local observers in the Mekong Delta have described Hòa Hảo altars as deliberately simple, often aniconic or marked only by calligraphic inscriptions of devotional phrases rather than large sculpted Buddhas.
Another distinguishing doctrinal point is the tradition’s critique of clericalism. The founder’s sermons often disparage ostentatious pagoda ceremonies and argue that lay households can perform the essential acts of veneration and moral cultivation. Adherents hold that this stance opens the path to spiritual practice for ordinary villagers who cannot devote themselves to monastic life. Historically this led to a practice in which small home shrines, recitation of short prayers, and observance of ethical precepts replaced grand temple liturgy for many followers. The tension here is palpable: doctrinally Hòa Hảo affirms canonical Buddhist principles such as compassion and non‑harm, while practically de‑emphasizing the institutional forms — monks, monasteries, and ritual specialists — that have organized much of Vietnamese Buddhism for centuries. Some communities, however, moved in different directions, establishing larger halls and lay organizations that adopted quasi-clerical structures; historians have documented a spectrum from strictly home-centered devotion to more organized, public forms of communal worship.
On soteriology (the doctrine of salvation), Hòa Hảo stresses moral purification and social harmony rather than elaborate metaphysical depictions of nirvāṇa. Adherents hold that moral reform in the present life improves both individual destiny and communal conditions; eschatological promises, when present, are grounded in ethical transformation rather than in metaphysical speculation. This emphasis on ethical correction and social betterment has been characterized by some scholars as a pragmatic, this-worldly soteriology: liberation is measured by improved conduct, reputational standing, and the amelioration of suffering in village life. Comparatively, this presents a tension with some strands of Mahāyāna that emphasize bodhisattva vows, devotional cosmologies involving cosmic Buddhas, or complex doctrines of emptiness; Hòa Hảo’s language is generally less cosmic and more practical.
Scriptural authority in Hòa Hảo centers on vernacular sermons and sayings attributed to the founder rather than on classical Pāli or Sanskrit canons. Adherents treat these collected teachings as authoritative guidance for life, circulating them in short pamphlets, song-like recitations, and oral readings at household gatherings. Historians and textual scholars note that these vernacular texts were disseminated widely in the 1940s and 1950s via simple printed leaflets and itinerant preachers; while not canonical in the classical Buddhist sense, they function as the primary doctrinal corpus for followers. The difference between canonical Theravāda texts or Mahāyāna sutras and the Hòa Hảo corpus is thus one of genre and social function: Hòa Hảo’s texts are pastoral handbooks for lay life, aimed at moral instruction and village reform rather than scholastic debate.
Hòa Hảo’s ethical orientation also addresses social justice and communal solidarity, at times entering the political sphere. Adherents interpret the founder’s exhortations as calls to protect villages, aid the poor, and resist moral corruption among officials. In the mid‑twentieth century, particularly during the upheavals of the 1940s and 1950s in southern Vietnam, this ethical platform overlapped with mobilizations for local defense and social order; historians describe instances in which Hòa Hảo networks coordinated mutual aid, organized local policing, and asserted political influence in rural districts. Some scholars read these activities as a form of engaged religion: ritual and ethical teaching that legitimizes local forms of governance and social organization. Interpretations of Hòa Hảo’s political role remain contested among historians and political scientists, with divergent assessments of whether the movement’s leaders sought primarily religious renewal, local autonomy, or broader political power.
Gender and family roles are another prominent feature of the tradition’s worldview. Hòa Hảo teachings emphasize family harmony, the duties of wives and husbands, and the importance of filial piety. Women participate actively in the movement’s devotional life, and many local rituals are organized around household observances; female involvement has included prayer groups, mutual aid societies, and religious instruction within the family. This emphasis situates Hòa Hảo within a Confucian‑influenced Southeast Asian moral universe even as it draws primarily on Buddhist motifs. Scholars of gender and religion note that Hòa Hảo’s lay orientation both reinforces traditional domestic responsibilities and creates spaces in which women exercise religious and social influence at the village level.
Finally, Hòa Hảo’s theological modesty — its preference for short prayers, personal piety, and ethical instruction — creates both distinctive identity and ongoing tensions. Some followers later institutionalized rituals and built halls and shrines in regional centers and urban neighborhoods; others maintained aniconic, home‑centered devotion. This internal diversity reflects the underlying doctrinal openness of the tradition: core commitments (compassion, moral reform, lay practice) coexist with differing opinions about organization and public ritual. The result is a living religious worldview, strongly localized in the Mekong Delta and present in diaspora communities abroad, that resists easy classification and must be read as simultaneously vernacular Buddhist, rural reform movement, and social ethic.
