There is give and take in the two planes through which a soul has to pass, a give and take between the souls who are going from the source towards manifestation and the souls who are returning from manifestation towards the goal. As a traveler coming from Asia to America and a traveler going from America to Asia who meet in Europe exchange money and thoughts with one another, so those souls take upon themselves the debts of one another, the knowledge of one another, the happiness, the misery of one another. In the same way we experience our life on earth. One soul, without knowing it sometimes, may take a route which leads him to riches, to success. Another soul may take a route that leads him to failure, to errors. It all depends upon what route they have taken from the beginning.
