Satipatthana

[one_awakening]

With the Satipatthana Sutta, The Buddha outlined what things we need to be mindful of, but did he recommend we maintain mindfulness throughout the day?

The answer to your question is in the sutta itself:

[2] "Furthermore, when walking, the monk discerns, 'I am walking.' When standing, he discerns, 'I am standing.' When sitting, he discerns, 'I am sitting.' When lying down, he discerns, 'I am lying down.' Or however his body is disposed, that is how he discerns it.

"In this way he remains focused internally on the body in & of itself, or focused externally... unsustained by anything in the world. This is how a monk remains focused on the body in & of itself.

[3] "Furthermore, when going forward & returning, he makes himself fully alert; when looking toward & looking away... when bending & extending his limbs... when carrying his outer cloak, his upper robe & his bowl... when eating, drinking, chewing, & savoring... when urinating & defecating... when walking, standing, sitting, falling asleep, waking up, talking, & remaining silent, he makes himself fully alert.

"In this way he remains focused internally on the body in & of itself, or focused externally... unsustained by anything in the world. This is how a monk remains focused on the body in & of itself.
