Meaning of one’s birthday

Sweet Mother,

What is the meaning of one’s birthday, apart from its commemorative character? How can one take advantage of this occasion?

A ) Because of the rhythm of the universal forces, a person is supposed to have a special receptivity on his birthday each year. He can therefore take advantage of this receptivity by making good resolutions and fresh progress on the path of his integral development.
