Question: When the soul chooses a new body, does it have a blueprint laid out as to its mission, or does the soul's mission evolve during one's lifetime, depending on circumstances and environment?

Sri Chinmoy: The soul always comes down to earth with a certain mission. However, the earthly environment can help or hinder this mission. It also happens that the soul, at times willingly, makes an adjustment to its surroundings. Then it gradually tries to fulfil its mission with the full recognition and co-operation of the environment.
