In educational institutions The
wai khru ceremonies which take place in most educational institutions in Thailand today generally follow the same form. The ceremony usually begins with a Buddhist devotion in institutions where
Theravada Buddhism is observed as the official religion, followed by the students' recitation of the
wai khru chant, which expresses respect for and gratitude to the teachers, and asks for the teachers' blessing of their studies. Following this, a select number of students, usually the representatives of each class, will present the teachers with offerings of flowers, candles and
joss sticks arranged on
phan (traditional Thai pedestalled trays). This is usually followed by a speech by the headteacher offering the students guidance in their academic career. Many institutions also present student awards and honours during the ceremony. The traditional offerings for
wai khru represent a symbolism of student qualities, namely: •
Ixora (
khem, ) flowers, which while closed form pointed buds, symbolizing sharp wit, •
Cynodon dactylon (
ya phraek, or Bermuda grass), the rapid growth and resilience of which symbolize perseverance and the ability to learn, • Popped rice (
khao tok, ), which symbolizes discipline, and •
Eggplant flowers, which bow low when nearing fruiting, symbolizing respect and humility. The ceremony is usually held shortly after the beginning of the first term, on a Thursday, as Thursday is traditionally the day of
Brihaspati, Vedic god of wisdom and teachers.
Wai khru ceremonies typically give thanks to a medicine practitioner's lineage of teachers, beginning with the most recent living teachers and culminating with
Jīvaka Komārabhacca, the legendary doctor of the
Buddha in the
Pāli Canon. Various other divine figures, such as deities,
rishi, and other spirits are often also recognized.
Wai khru ceremonies typically involve chanting
incantations in Pāli, Sanskrit, and Thai, which frequently include passages of scripture honoring the Buddha.
Wai khru ceremonies are conducted privately by individual healers, and also can be large community events hosted by traditional medicine schools or other institutions. ==Criticism==
