The irony of annihilation and love
To be annihilated sounds like condemnation, but in this book, Love explains that it is for love that God purges human souls of iniquity and brokenness, bring them to completion as they are unified with God in true oneness. The irony is that to become fulfilled, things are taken away, not added. The fulfillment of love is to be removed from the desires of this life, away from the ego—a lot like Buddhist philosophy in fact.
The irony of reason
Reason tries in vain to get his mind around what Love is teaching in this book. Reason asks Love why God would be so counterintuitive, and Love answers him that God's desire to be known is more immediate and direct that knowledge and logic are capable of. The reason that reason is insufficient is because the truth will be known in ecstatic oneness with God through bliss. Bliss is offered as a substitute for ideas and beliefs.
Oneness with God and the church
The church killed this author for writing this. That is ironic, but especially when the reader considers how similar their murder of the author was to the murder of Jesus by his own religious community. They are surprisingly far from Jesus, while Marguerite is literally embodying Jesus's martyrdom, because she urges her reader to pursue oneness with God without strictly obeying Christian dogma. She urges her readers to try finding God for themselves. It's ironically religious, and it's ironically anti-organized religion.
The irony of sin
Sin is offered as a false lead. People sin because they want to be one with God, but they are perplexed by self and ego, which make them serve their own interests. By love, Love says that sin can be extricated from the human soul by the fulfillment of desire. The irony of sin is that humans would intentionally ignore moral beliefs in order to attain more happiness, which comes from God. This removal is an annihilation of the soul, says Marguerite.
The irony of divine nature
The question of the book seems to be about the ineffable nature of divine love. For one thing, this writer seems to understand the human soul to have divine qualities of its own, so that the soul is immortal even when parts of the soul die, like the body for instance, and the mind, and also sin, and the various annihilations that Marguerite analyzes. The irony is that the Church only acknowledge the deity of Jesus, but Marguerite claims that all souls are one with the creator in essence.
