Have you never suffered for love? Besides, the Buddha said, “Love others as you love yourself.” (Bhadramayakara vyakarana sutra, 91)
The Four Truths are framed as a medical diagnosis:
- Diagnose the problem: Suffering.
- The cause of the problem: Selfish desire.
- Is the problem curable: Stop the selfish desire.
- The prescription: The eight-fold path.
This is a medical diagnosis, focused on curing the problem. It is not a philosophical description of the world. By and large the Buddha avoided such things, though his later followers did not do as well.
It is a common error to see nirvana as extinction. That is not the case. What nirvana extinguishes is mistaken notions about ourselves. It is like removing the ‘water’ from a mirage. We are no longer fooled by the mirage, but see it for what it is. All we have lost is the ‘water’ in the mirage.
No. The Buddha lived for many years after attaining nirvana. Thomas Merton also lived after, very probably, becoming enlightened. No doubt there are others as well.
Death is easy. Everyone who is born will die. The difficult trick is
not to be born again after you die.
Do angels exist? We can be reborn as angels, devils, in a (temporary) heaven, in a (temporary) hell. The Hindu/Buddhist universe goes in cycles. Part of the cycle only has the non-material elements. The rest of the cycle has both the material and non-material elements. Reincarnations are not “endless”; nirvana ends them.
If you throw a rock directly up in the air, you will in future be hit on the head by a descending rock. If you do not want to be hit on the head by a rock, then don’t throw rocks in the air.
Mind precedes all conditions,
mind is their chief, they are mind-made.
If you speak or act with an evil mind then suffering will follow you,
as the wheel follows the draught ox.
Mind precedes all conditions,
mind is their chief, they are mind-made.
If you speak or act with a pure mind then happiness will follow you,
as a shadow that never leaves.
– Dhammapada 1:1-2
Here is an extract from Chapter One of the Lotus sutra, the
Saddharmapundarika:
Sakra, the ruler of the celestials, with twenty thousand gods, his followers, such as the god Chandra (the Moon), the god Surya (the Sun), the god Samantagandha (the Wind), the god Ratnaprabha, the god Avabhasaprabha, and others; further, the four great rulers of the cardinal points with thirty thousand gods in their train, viz. the great ruler Virudhaka, the great ruler Virupaksha, the great ruler Dhritarashtra, and the great ruler Vaisravana; the god Ishvara and the god Maheshvara, each followed by thirty thousand gods; further, Brahma Sahdmpati and his twelve thousand followers, the Brahmakayika gods, amongst whom Brahma Sikhin and Brahma Gyotishprabha, with the other twelve thousand Brahmakayika gods.
We have tens of thousands of gods.
There is no “entity”. Karma is not an entity, any more than there was an “entity” throwing that rock back down onto your head. If you do require an entity, then that entity is yourself. You threw the rock in the air; you suffer the consequences. Actions have consequences. If you don’t want the consequences, then don’t do the actions. It really is that simple.
And if the universe is being run by a omnipotent Abrahamic entity, why is it so cruel? Thousands and thousands of centuries of plagues and wars and starvation and murders. Please explain.
Exactly, we’ll make a Buddhist of you yet.

You just need to realise that the hells are not permanent, more like purgatory.
It has, but that effect was mostly in Asia, not in Europe. Christianity has had more effect in Europe.
A word of advice. I have probably spent more time arguing these things with Christians than you have arguing with Buddhists. You might want to bear that in mind.
