Karma or Karm is the self-effort or work put behind all actions. Luck is the result of self-effort, including self-effort from past lifetimes.
- Bhagwad Gita:
Should keep doing your work, but do not have hopes to enjoy fruits of the labour.
- Ashtavakra Gita:
The Body is just an observer, the Soul is the do'er. The Body should not desire to enjoy the pleasures of labour by the Soul.
