Is the Experience of Love a requirement of Enlightenment?
If so, can it occur before merging with the Oneness? Does it need to occur at the time of merging? Is it acceptable to become Enlightened and discover Love afterwards?

When you are confirming an Enlightenment which is what We think you are asking, when they have merged with the Oneness as long as they can answer, with conviction, the questions set before them, you can say they are Enlightened.

It is so much better to have the Love Realization in place during the time they are Meditating, as it makes the Enlightenment more concrete and solid. However, it doesn’t matter when the Love Realization comes, they are still Enlightened.
