Wisdom is tolerance of cognitive dissonance.

That love, in the sense of wishing their happiness, will cause your actions to be effective in relation to that person.

You can't relate to an absolute or it wouldn't be absolute, it would be relative. On an intellectual level, that's easy. However, you hear theologians in the theistic traditions talk about absolute God, and I saw God, or God spoke; speaking, being seen, these are all relational things. So what is absolute about such a being, wouldn't actually be absolute.

If you see really bright lights, or hear really loud noises, go towards them, don't run away from anything. It's like giving someone instructions on how to handle a bear, don't run away from it. Stand up and try to make yourself look as big as possible. Don't give it the signal that it should chase you. And that's the case with the after death visions. Don't go for dark seductive lights, go only for bright lights.

Practice giving things away, not just things you don't care about, but things you do like. Remember, it is not the size of a gift, it is its quality and the amount of mental attachment you overcome that count. So don't bankrupt yourself on a momentary positive impulse, only to regret it later. Give thought to giving. Give small things, carefully, and observe the mental processes going along with the act of releasing the little thing you liked.

If your enemy is happy, then why would they be bothered to be your enemy? Being someone's enemy is no fun. It does not add to happiness.

The most important enemy for everyone is their own illusion that makes them unrealistic or exaggerates their sense of self-importance in the world. Ironically, you're the super secret enemy. Whether lay or householder, everyone has that internal enemy.
