Janma begins the board with birth: entering a life whose conditions you did not entirely choose. In Leela Guide, a six brings you into the game through square 1 and takes you to square 6, Delusion.
A beginning rarely comes with complete understanding. You may know that something needs to change without knowing how it will unfold. Birth offers a way to consider what is already present: your circumstances, the people around you and the question you want to bring to the game.
You do not have to invent a new identity before taking a first step. A useful beginning might be naming what matters now and noticing what support you have.
