Occult is another name for 'hidden' knowledge.
Meditation is common to all cultures and religious systems.
There are hundreds of techniques with different aims.
It's common in all systems to learn to still the mental chatter in order to apply different techniques for various outcomes.
One of the reasons that people meditate is to transcend the 'little ego' and have a personal experience of connectedness with the universal consciousness.
Some western religious political agendas realised that if too many of their obedient flock realised their own divinity then the power base of the church was on shaky ground, hence the fear and smear campaign.
Taking control of your own chattering mind is very enpowering. The power it creates is neutral, neither good nor bad in itself. Most people experience waves of loving energy whilst in meditative states, and their personal energy vibrates at a higher rate, opening higher perceptions.
Some church politicians never approach this higher state of awareness and in their ignorance seek to control by rules and fear. Others are fully aware of the freedom gained and deliberately suppress the knowledge.
In recent years science has allowed us to take a look at what is happening in the brains of experienced meditators, and to categorise and label the results that they observed.
It is very pleasant and beneficial for your health in so many ways to be able to control your own state of mind and observe your own thought processes.And if you should be seeking spiritual enlightenment, no amount of studying can take the place of daily meditation. You will never have higher awareness until you learn to silence the mind. We are so much more than this body. So few people understand what they really are. Meditation will help you to uncover your true identity, and that is nothing to fear surely?
