Īryāpatha

īryāpatha (P. Iriyāpatha; T. spyod lam; C. weiyi 威儀) is translated as "movement," etc.

This term commonly refers to a set of four types of "postures" or "physical movements" that are referred to in meditation instructions.

These four postures are:

• walking (caṅkrama; P. caraṃ)
• standing (sthāna; P. ṭhāna;)
• sitting (niṣaṇṇa; P. nisinna)
• lying down (śaya/śayana; P. sayaṃ/sayāna)

For example, the Karaniya Metta Sutta states:

With loving-kindness for the whole world should one
Cultivate a boundless heart,
Above, below, and all around
Without obstruction, without hate and without ill-will.
Standing or walking, sitting or lying down,
Whenever one is awake,
May one stay with this recollection.
This is called a sublime abiding, here and now.

The Princeton Dictionary states:

Because the body was presumed typically to be always in one or another of these postures, they constituted specific objects of mindfulness of the body (kāyānupaśyanā; P. kāyānupassanā; see also smṛtyupasthāna)...

The Princeton Dictionary also states:

The term īryāpatha can refer in other contexts to general behavior or “deportment” (but typically to religiously salutary deportment) or to a specific “course” of religious and/or ascetic practice.
