This was really helpful Rev_Vesta(Is it from Goddess Vesta?).

According to my experience the best way to open the chakras is by allowing the Divine open them for you

Simple methods seems to work best. They are more practical too.
Just by gently feeling the chakra with your mind activates it or you can imagine a chakra being filled with golden white sunlight. There's a principle in yoga science that says: "where you put your thought into is activated". It's the core of all mind exercises.

There are various shortcuts to waking/opening up all the chakras at once.
You don't really have to work on your chakras one at a time unless you necessarily want. I have explored chakras that way too, but there are better ways.

For example you can wake up the lamp of life (pituitary gland/"fourth eye") and sunlight heart (thymus gland/heart center) and the rest will follow.

I will expound this subject a little further.

There are lots of written information about chakras nowadays and based on what I've read, this information is mixed with a lot of nonsense. You can get very detailed describtions of the chakras, altough in reality you can learn to open them up if you just know their locations and few other simple things.

I've had an opportunity and a priviledge to study under a true yogi. One on one. One of the first things that I was amazed about him was certain kind of simplicity in his teaching. All nonsense was stripped away. And what was the most remarkable thing was the fact that he taught me the foundation science (and principles) on which all meditation paths and techniques are based on. This way I could understand how and why different techniques work. This has saved a lot of time. Basically the knowledge he transmitted to me together with God's loving Grace gave me a change to start where he was at that point. So based on my experience things can be streamlined and speeded up a lot by right knowledge.

And one thing that I've noticed about chakra information in todays world is that it seems to be often mixed with self concept programming. What I mean is that psychological qualities of a person are mixed with the qualities of the chakras and how open they are. They are connected but you can also bypass self concept progamming and stimulate chakras directly on purpose. This is why you can be 'bad' and have open chakras. Having "higher" chakras open doesn't automatically make you a saint either. Mixing open chakras with saintliness has given a possibility for some spiritual teachers/leaders a possibility to exploit their position. Chakras is basically a neutral reality. So from this we can conclude that knowledge can be used for good or bad.

I wanted to make this point clear as a warning. The knowledge that I'm going to share (if someone shows interest) will give a person an opportunity to become really powerful and it will be relatively easy to accomplish. The problem is that the power is a trap. So in an ideal situation you are a person who's motivation is based on Love not power.

Nnt your avatar picture has one of the Keys

If you study the similarities between your avatar picture (unicorn) and picture below, you will find it.

If you just place your thought into the Eye of Sun (in front of the top forehead) and the Heart center (in the middle of the chest) (feel them with your mind) the rest will follow automatically.

The simplest way to find the Eye of Sun area with your mind is to put on a baseball cap with the brim foreward and then tilt the brim of it upward at/to a "forty-five" degree angle from horizonal. Now look at yourself in the mirror  you will notice the effect that looking at yourself has on your nervous system. What you are experiencing is your pituitary gland "on" and "charging" your body physical energy system.

The simple way to activate the Heart center is to visualize the sun in your heart center and feel its warmth and see its light. This simple mind exercise will stimulate your immune system on purpose. And you are using your mind to stimulate/affect your autonomic nervous system to create healthful benefits for yourself and those around you.
Because, what you feel affects you and those around you.

It should be understood that this simple meditations leads you to Awakening but it doesn't necessary have anything to do with God unless you want.

To add God to this you must desire and allow God to live within you (you are His temple) and love his presence. Then you allow the Holy Spirit to flow from Heaven to your forehead and chest and nourish the Divine presence within you. This will automatically activate everything.
