What is the single best way to open chakras? In what way can you become more divine? Is there a tried tested way to master all chakras?
Can something be said about chakra meditation? Chakra meditation is the way to open and then activate chakras. The chakras which are metaphysical and psychometaphysical storehouses of spiritual and conscious energy are found at eight human body locations.

Chakra Meditation
The location of chakras are (coccyx, sacrum, mid low back, heart center, throat center, third eye/brow, and crown or top of head and feet) found in certain areas of the back and feet. What you may ask is the process of opening these metaphysical locations. Meditation.
Meditation or allowing consciousness and spiritual energy or kundalini to move through from base (coccyx) up through each subsequent chakra is the only way to allow consciousness to expand. Why is this important. Conscious wills expansion. As the cosmos is moving to expansion (remember that the cosmos and God is consciousness) so too the soul (God and your divine cosmic source or Soul) also reflective and built in the image of God, also wants expansion.
What does it mean to have your chakras open? Chakras that open bring with it new expansion of ideas, creative ability, health, spiritual powers, divinity, and even cosmic influence.
Two quick ways to open the chakras are Kriyas (pranayama) and meditation. One effective pranayama is to sit comfortably, roll the tongue up and backward to the back and top of the throat, breathing in slowly and controlled while mentally counting up as high as breath allows. The expiration (also mental counting) should be twice as long as inbreath.
In this way you will circulate consciousness and open chakras, activating them, and allowing consciousness to expand. After or even on its own, do some simple mindful meditation (allowing all thoughts, memories, feelings, sensations, ideas, emotions or any other thought form to pass through the mind without attachment) which is by far alongside kriyas is the second most powerful chakra meditation.
