This is strange. Explaining stuff to myself.

[Little Rik]

Don't worry about Alex Crossless.
He only bark but doesn't bite.  

The guy doesn't know that religions originate from pure spirituality so it is obvious that Hinduism originate from yoga as it is obvious that Christianity originate from Jesus' spirituality and also Buddhism originate from the same yoga that Shiva and Krishna were teaching.  

That Hinduism got its origins from yoga is not 'obvious'. The word 'yoga', as far as I can determine based on an online search, is first mentioned in the Rig Veda. Whether the Vedic religion adopted yoga as practiced by outside groups like the Vratyas, or whether it developed yoga itself prior to the Vedas being written is unclear to me.

As for religions originating from "pure spirituality", something more than a mere claim will be needed. Do you mean to say that it's true of all religions? Put me down as skeptical.

Suppose I tell you something.
After sometime you tell somebody else what I did tell you.
After some other time that guy which you told him something about me tell somebody else what he remember that was told to him and the thing goes on and on for sometime.
Do you really think that the original story is the same as the last one?
This is one problem that prevent the real story from staying the same.
The other and most serious problem is that as the time goes by the original teaching is changed because
people always try to twist the original teaching in order to make it easy for them to follow.
And the last is that priests try to become intermediaries between God and the masses in order to sit in the chair of power. In this way they have to invent all sort of lies like hell in order to mentally control the masses.

As the food become stale after sometime also the old teaching become stale and the real McCoy is lost.
This is how pure spirituality become a religion.
Shiva, Krishna, Buddha, Jesus and others never talk about devils and hell but those religions that suppose to follow these spiritual beings do.

Now the last point.
How do I know this?
Anybody can if they really want.
Easy.
The connection between us and God is open 24/7.
If you are sincere and your reason to know is pure and devoid of any selfish interests then God will let you know.
There is a saying Cross and that goes.........WHEN THE STUDENT IS READY THE TEACHER WILL APPEAR.
