Buddhānusmṛti (Sanskrit; Pali: buddhānussaṭi), meaning "buddha-mindfulness", is a common Buddhist practice in all Buddhist traditions which involves meditating with a buddha as the meditation subject.
In all Theravada countries chanting, devotion (bhatti) and worship (puja) is a big part of lay and monastic Buddhist practice, and devotional chants which praise the qualities of the Buddha are widely used. Buddhānussaṭi is considered one of the four "Guardian meditations", as well as part of the "Ten Recollections" and the "forty meditation subjects" (Kammaṭṭhāna) which also includes recollection of the Dharma, Sangha, morality, generosity and Devas. According to Thanissaro Bhikkhu, recollection of the Buddha is meant to "induce a sense of joy and confidence (pasada) in the practice" that "can bring the mind to concentration and cleanse it of defilement." In the Pali Nikayas' mention of the ten recollections, Buddhānussaṭi is defined thus:
One thing — when developed & pursued — leads solely to disenchantment, to dispassion, to cessation, to stilling, to direct knowledge, to self-awakening, to Unbinding. Which one thing? Recollection of the Buddha. This is one thing that — when developed & pursued — leads solely to disenchantment, to dispassion, to cessation, to stilling, to direct knowledge, to self-awakening, to Unbinding. - AN 1.287-296
The most widely used meditation text in Theravada Buddhism, the Visuddhimagga uses the following 'Buddhānussaṭi Gatha' for contemplation of the Buddha's nine qualities (Nava Guna):
Iti’ pi so bhagava araham sammasambuddho vijjacaranasampanno sugato lokavidu anuttaro purisadammasarathi sattha devamanussanam buddho bhagava’ti.
"Thus indeed is the Exalted One (1) an accomplished one, (2) a fully-enlightened one, (3) endowed with knowledge and good conduct, (4) well gone or gone to bliss, (5) a knower of the world, (6) an unsurpassed leader of persons to be tamed, (7) a teacher of humans and devas, (8) the awakened or the one who knows, (9) the sublime or exalted."
