noun
free from worldly or worthless thoughts
A yojijukugo describing a state of mental emptiness or detachment from distracting, mundane, or unwholesome thoughts, often associated with Zen or meditative practice.
座禅を組んで無念無想の境地に入る。
I sit in zazen and enter a state free from worldly thoughts.
無心 also means 'innocence' or 'free from distracting thoughts', but is more common and can also mean 'begging' or 'asking for something' in other contexts. 無念無想 is more explicitly about a meditative state of no-thought.
A yojijukugo composed of 無念 (no thought, no worldly concern) and 無想 (no conception, no mental image). The exact historical derivation is uncertain; it is conventionally associated with Buddhist meditation terminology.
