Patikulamanasikara

It refers to a traditional Buddhist meditation whereby thirty-one parts of the body are contemplated in a variety of ways.

In addition to developing sati (mindfulness) and samādhi (concentration), this form of meditation is considered conducive to overcoming desire and lust.

[2] Paṭikkūla (Pāli) literally means "against" (paṭi) "the slope" or "embankment" (kūla) and has been translated adjectivally as "averse, objectionable, contrary, disagreeable" and, in its nounal form, as "loathsomeness, impurity".

Sariputta declares that meditating on these 31 body parts leads to "the attainment of vision, in four ways", and briefly outlines how this method can be used as a springboard by which one "comes to know the unbroken stream of human consciousness that is not established either in this world or in the next".

[11] In addition, in the Iddhipāda-samyutta's Vibhanga Sutta (SN 51.20), this meditation subject is used to develop the four bases of power (iddhipāda) by which one is able to achieve liberation from suffering.

[19] The Visuddhimagga suggests the enumeration of the 31 body parts implicitly includes the brain in aṭṭhimiñjaṃ, which is traditionally translated as "bone marrow".
