Thank you so much. This really helps. I've always found that sometimes the most profound truths are the ones that are easiest to grasp. I'm currently working on my psychic development and spirit guides, and I have a tendency to question everything I hear, which is a good thing, but sometimes it's hard to trust my spirit guides. i'm also a singer too, and boy, can it get complex in terms of having to know all the muscles.

In my opinion--which based on what I had experienced, it's not good to open more than 1 chakra simultaneously. It had caused me troubles from physical pains. Chakras are like the needles of a clock, so any chakra that turns(opens) would consequently make the others turn too. So it's enough to open just one and the others would follow.
    It's not hard actually, to get any technique to open up the chakras. Everything is energy, so what we need is how to activate the energy through "physical tools", or on other word: to manipulate the unseen through the seen. The keyword is "As above, so below". I would give an example:

1. For Sahasrara(Crown) Chakra: It's place is on the top of the head. Top of the head is the place where hair grows; & hair
  means perfection because without it--like a bald man--someone would have unperfect condition. Next we can find the  
  synonims: Perfection=Whole=Ending. From there we can find the appropriate names. Among them are: Elohim, Isis,
  Mary(Madonna), Guan Yin(Kuan Yin), Shiva, Brigit. All the names I had mentioned have the attribute of wholeness, source or
  change(from Ending).
2. Agya(Third Eye) Chakra: Related to face. Face has important role with how we perceive our surroundings, our reality.  
   Reality=Consciousness=World/Earth(from surroundings)=Creation/Creating. Some of the appropriate names: Buddha, Geb,
   Brahma, Gaia.

   You can use any mantra related to them, or any ritual, or whatsoever. You can even use those names as mantra. From The Bible in The Book of Creation we could found that the number 7 also related to perfection(the day when The Almighty finished with the work of creation). So we can also use 7 strokes--you can use any tool--repeatedly(laike chanting) to activate Sahasrara Chakra.
    Try to learn symbolism. I learned symbolism initially by reading The Bible everyday, by relating what I read, not as something had happened long, long time ago in the Middle East, but as something that happening "inside me".
   Though you didn't ever received any initiation, it doesn't matter, because all things are actually energy so what we do physically would surely have effect on them. If the effect is small compared to one who initiated, then that's the only difference. But gradually your ability would grow stronger and stronger--just like if we're learning something(like at school), our knowledge and ability of what we learned would definitely increase.
