If you a person who wants to have more "ahh hah" moments of wonder in your life, or personal promptings and guidance, or perhaps to experience nirvana or a kundalini, the type of Qi Cultivation for you would be to focus on the Qi cultivation of the chakra energies.
If you desire to improve or change the world, or even create miracles,the Qi cultivation you may want to consider focusing on GROUP Qi cultivation, where you bring several people with similar goals together and focus the groups intention towards a positive change or outcome.
Qi Cultivation opens your mind to an awareness beyond the physical, and with that open door, many new experiences are there to be explored and experienced. It essentially is up to you what you want to experience, explore, or use. First comes the awareness, then a desire, then creating the ability, and then having the experience.
Qi Cultivation is something available to everyone. It is just a matter of accepting what is possible, and then opening that door.
