na-adjective
unworldly; supermundane; free from worldly cares
Describes a person, attitude, or lifestyle that transcends ordinary worldly concerns; often carries a spiritual or philosophical tone.
彼の超世俗的な考え方に、私は深く感銘を受けた。
I was deeply impressed by his unworldly way of thinking.
その僧は超世俗的な生活を送っている。

世俗的 means 'worldly' or 'secular', focusing on ordinary, material concerns; 超世俗的 adds the prefix 超 (transcending) to mean rising above such concerns.
Compound of 超 (chō, 'transcending') + 世俗的 (sezokuteki, 'worldly, secular'). The exact historical derivation is uncertain, but the word follows a productive pattern of forming abstract adjectives with 的.
