Bhagavad Gita · Chapter 18: Freedom through Renunciation

Bhagavad Gita 18.14

adhiṣṭhānaṃ tathā kartā karaṇaṃ ca pṛthagvidham | vividhāśca pṛthakceṣṭā daivaṃ caivātra pañcamam ||

The body as the seat of action, the doer, the various instruments, the different kinds of effort, and, as the fifth, what is ordained by the divine.

Modern context

The five causes of any action: the body, the doer, the instruments, the efforts, and daiva, what is ordained beyond human control. The fifth is important. Every action involves factors no one can command: timing, chance, the choices of others, forces of nature. Anyone who has worked hard on something and seen it succeed or fail for reasons beyond their reach knows this fifth cause.
