Exactly! Therein lies the catch-22 as I mentioned earlier.
The wise realize it is nigh impossible to stay on an elevated platform of spiritual goodness without taking shelter of God.
Brahman gives you the option to do it on your own but can you? That is the point. The funny thing is that the "good atheists" are unknowingly following the dharma and hence IN Brahman. Don't tell them that
However, OP is not Hindu and not scripture.
Those Bramhan-vAdis who abide in the Oneness of Brahman and may say "I do not do any puja to form of God" are either
(i) already on that purified elevated platform from many lives of polishing, to be now shining gold and abiding in Brahman. This is jnAna yoga.
OR
(ii) They could very well be deluded, and in mAyA and the dangerous slippery slope of falling off-track into less-than-goodness is quite there. They have to be careful.
So the choice is ours -- be the manjara -- let God carry you like cat carries kitten
OR
Make your own efforts. Like the baby monkey that holds onto God
OR
Now you are the grown-up monkey - all on your own but with the virtues embibed
--
Point is, let's not mix up those on the dhArmic good platform (who implicitly are best abiding in God and radiating His virtues)
with
The ignorant ones who simply reject
These are 2 different things.
I think we also have a different outlook at what it means to worship God. I believe God has provided scripture, but scripture calls to a reality known as God's face or name, and that is how to connect to him.
The face of God is not something we choose, so we don't get to choose who represents in the outward world (leaders, gurus, avatars, etc) or inward world (Angels, Spirits, gods, etc), but have to find those who he sent with proofs.
We have to find proofs - because the intentions has to be to submit to God.
There is no doubt spirituality in spiritual realms that Jinn provide and the Jinn all like humans believe they are guided. Quran describes Devils as leading astray while believing they are guided.
This thought that Satan and his forces are malicious is true and untrue. Deep inside, the intention of Iblis and his forces, is they deceive themselves and want everyone to deviate with their non-submission. It's the same intention of disbelievers (who believe they are guided), when Quran says they wish you to leave it as they leave it, or abandon as they abandon. But they are not evil in the sense they tell themselves let's go harm others and misguide others purposely. They tell themselves they are good.
For us who can detect energies, we have to make a choice. Do we trust every person who talks about energy because of reputation of humans or do we seek a proofs from God.
I believe in this time, Quran towers over all literature and provides proof to follow the Messenger and Possessors of the Authority that are his successors.
I believe God can provide miracles, but in this time, has hidden them because of what previous generations did with them and with their followers, but last left the Quran as a miracle.
God is capable of providing proof.
It's not that I doubt Gurus have mystic levels of experience and that they enter realms that are no doubt real, it's these sky realities and realms, are not of the light, they are mixed of darkness and light. And the beings providing psychic powers etc, to their followers, are not reliable holy spirits, but they themselves are not malicious, they want to guide humans too.
At the end, though, these beings - be they called gods or otherwise, or sons or daughters of God, to me, they witness the holy spirit in God's chosen Prophets, Messengers, and holy ladies, and Guides, and also witness the Angels that are chosen, yet they in arrogance think they are above that for similar reasons people rejecting Islamic morality.
But with the Jinn, the case of responding to the caller of God is more serious and more binding since they all witness the light of God and his forces.
Relying on these beings to see you are and witness who you are, is also, a source of blindness. We need to see with the proof of God's light and judgment.
Quran combines somethings our souls wish for and likes, and other judgments, we wish for example were not true. I'm sure a lot of Muslims wish they can marry polytheists or people who don't believe in sex after marriage and so do zina and never repent to it and hence forbidden, but we submit to God's guidance in that regard. We see the reasoning, not just what we wish for.
Some of us we have a hard time with the notion of hell. Of course, who wants humans going there? But justice is a reality. God is quick and severe in retribution, we can't change who God nor should we want to but be pleased and happy with who he is.
How to know the truth though? To me I choose to give God a chance, and found Quran reliable and the family of that reminder a reliable means with it.
