Each religion clearly sends a different message. I don't see how those messages can be reasonably reconciled unless you assume that every religious doctrine is a misinterpretation of one entity's will.
To some extent, yes, although it depends how they are interpreted. They could be seen as divinely revealed, or as human constructs to attempt to know the Divine, who is so beyond comprehension and human understanding that they're cultural interpretations.
The different gods are no problem from my perspective, really; the different gods can be seen as manifestations of this Supreme Divinity; I see the different gods as different facets of the attributes of this God, who exists as all (including us).
So, for example, Gaṇeśa, the Elephant-Headed God Manifestation of Hinduism, is the Lord of Removing Obstacles. I don't really believe he exists as an actual entity, sitting up in the sky, so no actual elephant head -- but its appearance translates like this:
And his story has a meaning behind it, too.
The same with Lord Narasiṃha, the half-man half-lion avatāra (avatar; "incarnation") of Lord Viṣṇu (the sustaining attribute of God). The story goes like this (and yes, I typed this by myself, except for a small bit here 'n there.
):
There's a rākśasa (a sort of humanoid demon) whose brother was killed by a previous incarnation of Viṣṇu (Varāha) because he was evil. The rākśasa wants revenge upon Viṣṇu, so he lives a life of austerity and worships Brahmā (the Attribute of Creation). After much time, Brahmā offers Hiryaṇyakaśipu a blessing; he can have any wish he desires.
"I wish for immortality," says Hiraṇyakaśipu. Brahmā refuses, but states he can offer him mortality with conditions.
So Hiraṇyakaśipu asks that he cannot be killed: inside a residence nor outside, at daytime or night, on the ground nor in the sky, by no weapons, by no humans nor animals, demigod, nāga nor demon, by living or non-living things or creatures created by him. In addition, to give him the "siddhis".
Brahmā agrees and blesses him, before vanishing. Hiraṇyakaśipu thinks he's won over death.
One day, Indra and other devas attack his home while he is performing austerities on a mountain. They spare Kayadu (Hiraṇyakaśipu's wife), who is sinless. She goes with the age Nārada (willingly) and his good influence affects her unborn baby. When born, his son Prahlāda, becomes an ardent worshipper of Viṣṇu, which angers his father, and decides to kill him, but each time he tries, he fails.
Prahlāda refuses to accept his father as the supreme Lord of the universe. Hiraṇyakaśipu asks his son if Viṣṇu is in this pillar of the house. Prahlāda answers he is in everything, which makes Hiraṇyakaśipu angry; he smashes the pillar and attempts to kill his son.
Then, Viṣṇu incarnates on earth (as Narasiṃha) and moves in defense of Prahlāda. In order not to upset the boon that was bestowed upon Hiraṇyakaśipu, he incarnates as Narasiṃha.
Hiraṇyakaśipu can not be killed by human, deva or animal; Narasiṃha is neither one of these as he is a form of Vishnu incarnate as a part-human, part-animal.
He attacks Hiraṇyakaśipu at twilight (not day or night) on the threshold of a courtyard (neither indoors nor out), and puts the demon on his thighs (neither earth nor space). Using his sharp fingernails (neither animate nor inanimate) as weapons, he disembowels and kills the demon.
After killing Hiraṇyakaśipu, Narasiṃha is furious, nobody is able to calm him down, except Prahlāda, whom he crowns king.
The story has many meanings, which is why I thought that I would share it:
1. Anyone can be blessed by God if they work hard, even a rākśasa.
2. Even if you try to outsmart God, you will never succeed.
3. No matter where you were born, you can be good and loved by God
4. Death will find a way.
5. God protects his devotees.
And much more; others can extract more. This is the beauty of religious scriptures, you can come back to them and continue to find more from the texts.
Do I believe it happened? Nope. But still. We in the West currently view myth as worthless. It isn't.
However, I respect the open-mindedness of your approach. If everyone lived like you, bigotry wouldn't be a problem.
Thank you.
