The redneck strike again.

[Confused Ape]

The system of teaching follow the same pattern.
Religions pop up out of spirituality.
Christ never teach the mass or the rosary so why today
those who say that believe in Christ follow rituals that Christ never teach?
Christ was teaching spirituality not rituals.
The same with Buddha.
He was teaching yoga meditation but these days how many so called
Buddhist practice meditation?
You go in the Buddhist temple and you will see people praying Buddha with some incense in the hands.
The same with Hinduists.
Lord Shiva and Lord Krisna were teaching meditation
but these day most of the followers chant old mantras
or try the nirvana with artificial means.

I looked up Shiva and Krishna teaching meditation.

Yoga Principle - Meditation Techniques

Many easy and proven meditation techniques are taken from many scriptures and sacred books. These meditation techniques are described here with the name of source scripture for reference

Scriptures and sacred books are a late development in human history.

Paeolithic religion

Religious behaviour is thought to have emerged by the Upper Paleolithic, before 30,000 years ago at the latest,[1] but behavioral patterns such as burial rites that one might characterize as religious - or as ancestral to religious behaviour - reach back into the Middle Paleolithic, as early as 300,000 years ago, coinciding with the first appearance of Homo neanderthalensis and Homo sapiens. Religious behaviour may combine (for example) ritual, spirituality, mythology and magical thinking or animism - aspects that may have had separate histories of development during the Middle Paleolithic before combining into "religion proper" of behavioral modernity.

The San are still living a hunter/gatherer lifestyle in South Africa and their religion includes Shamanic Trance

Psychologists have investigated hallucinations and altered states of consciousness in neuropsychology. They found that entoptic phenomena can occur through rhythmic dancing, music, sensory deprivation, hyperventilation, prolonged and intense concentration and migraines.[23]

Meanwhile, over in Amazonian Peru, people use Ayahuasca

People who have consumed ayahuasca report having spiritual revelations regarding their purpose on earth, the true nature of the universe as well as deep insight into how to be the best person they possibly can.[2] This is viewed by many as a spiritual awakening and what is often described as a rebirth.[3] In addition, it is often reported that individuals can gain access to higher spiritual dimensions and make contact with various spiritual or extra dimensional beings who can act as guides or healers.[4]

So which came first? Sophisticated meditation techniques or early humans accidentally discovering altered states of consciousness and developing shamanic style religions and spirituality as a way of explaining their experiences?

You can find young kids already skilled in something.
Nobody ever teach them that skill so where they got it from?
When i was in Fiji years ago i saw a 8 years old boy who could tell what was wrong with the engine of a car just by listen to the engine noise.
Beethoven and other great musicians displayed musical talents at an early age.
How could it be when they didn't spend years of learning at a conservatory?
In life you get something only if you work very hard so it is obvious that they developed those skills in past lives.

The Mind Of The Prodigy

More striking is that every single prodigy scored off the charts in working memory -- better than 99 percent of the general population. In fact, six out of the eight prodigies scored at the 99.9th percentile! Working memory isn't solely the ability to memorize a string of digits. That's short-term memory. Instead, working memory involves the ability to hold information in memory while being able to manipulate and process other incoming information. On the Stanford-Binet IQ test, working memory is measured in both the verbal and non-verbal domains and includes tasks such as processing sentences while having to remember the last word of each sentence, and recalling the location of blocks and numbers in the correct order in which they were presented. There have been many descriptions of the phenomenal working memory of prodigies, including a historical description of Mozart that involves his superior ability to memorize musical pieces and manipulate scores in his head.

The article then goes on to autism and prodigious savants.

The only other group of individuals known for their dazzling displays of memory in rule-based domains such art, music, and calendar calculating are prodigious savants. There are fewer than 100 known prodigious savants alive today. A major difference between savants and prodigies is that savants display high ability in the presence of great disability. Often that disability is severe, debilitating autism that impairs language and communication so much that it leaves an "island of genius" (although Daniel Tammet is an interesting and rare exception, in that he has highly functional autism as well as synesthesia). Ruthsatz and Urbach suggest that prodigies may have some sort of "modifier" that prevents them from displaying the more severe deficits seen in most savants.

Both prodigies and savants demonstrate extreme attention to detail, exceptional memories, and high ability in rule-based domains. This is probably not a coincidence, as all of these characteristics are associated with talent in these domains. But how? First of all, there's no such thing as "innate talent." No one is born with fully developed traits. That's not how genes work. It is possible, however, that prodigies are born with genetic variants that relate to various tendencies, including an attentional focus on details and a brain-network wiring that supports an enhanced encoding of new memories. This could explain why prodigies and savants frequently report that they were attracted early on to domains that deal with systems, and why many also display -- even in infancy -- an enhanced ability to maintain mental representations (although there's some evidence that the working memory of prodigies is most enhanced in the symbol systems that interest them the most, such as mathematical or linguistic stimuli). After just a few years of obsessive focus, prodigies build up rich long-term memory structures that allow them to assimilate and learn new information faster and faster. This could also explain their enhanced ability to manipulate information in their heads.

I'm going to finish this post with Orlando Serrell

Orlando L. Serrell (born 1968) is an "acquired savant" — someone who exhibits savant skills after CNS injury or disease, as opposed to a person born with autistic disorder or other developmental disability.

Orlando Serrell did not possess any special skills until he was struck by a baseball on the left side of his head on January 15, 1979 when he was ten years old. Serrell fell to the ground, but eventually got up and continued playing baseball. He did not get any medical treatment because he did not tell his parents; for a long while, he suffered from a headache.[1] Eventually, the headache ended, but Orlando soon noticed he had the ability to perform calendrical calculations of amazing complexity.[2] He can also recall the weather,[3] as well as (to a varying degree) where he was and what he has done for every day since the accident.[4]

I don't think that being hit by a baseball bat proves that amazing skills were developed in past lives.
