The word “bhāvanā” in general means meditation except in this text means pronouncing incantations. The first part of the text was written in Pali language and the last part contains various Buddhist khatha (incantations) for pronouncing.
Other notes:
Folio 6 on the verso side on the left margin: The text was written with blue ink says “khatha sut khao ban mai mueang mai” (the verse using for chanting at the ceremony for a new house or a new village).
