自然

(sa) svayaṃbhū, also 自爾; 法爾 self-existing, the self-existent; Brahmā, Viṣṇu, and others; in Chinese it is 'self-so', so of itself, natural, of course, spontaneous. It also means uncaused existence, certain sects of heretics 自然外道 denying Buddhist cause and effect and holding that things happen spontaneously.
