The happy marriage of Margaret Thompson and Peter Doyle is brought to an abrupt end by a dramatic traffic accident in which he dies and she is left blind. Margaret receives an important sum of money in compensation for these serious consequences, which is complemented by the no-less-important amount she receives as a beneficiary of the life insurance policy contracted by her late husband. Her comfortable economic situation attracts unscrupulous people, including Thomas Corbett, who pretends to be in love with her. Through an energetic message at a mental level from an ascended master called Santro –a disciple of the master Samitu– Margaret learns that she is a Great Soul, and shall be instructed in the esoteric mysteries in order that she may fulfill her mission on Earth prior to undergoing the ritual of Ascension. It is also revealed to her that Thomas is an impostor whose negative influence over her hinders her spiritual evolution. She experiences astral travel with Santro which will help her to unmask the Machiavellian character and the dark arts of the man who claims to love her. Once this episode is complete, Margaret dedicates herself to completing her mission until the day comes when she will undergo the Ascension ritual. In this new dimension in which she lives, she will meet her grandson Peter – a reincarnation of her husband– who died prematurely aged seventeen, shortly after his grandmother passed away.
