Yes it can be done but chances are, you won't be able to do it because the fact you need to ask the question tells me you don't have the skill of mind and soul to do it. But try it anyway, it will be good practice. Put 100% into trying the working and be consistent with it. Put as much - Energy. Will. Belief. Concentration and Emotion into the working as you can everytime you do it and do it relentlessly 40 days straight. Plus more.
And make sure on top of that you are doing void meditation and chakra empowering and breathing exercises and other meditation programs everyday to strengthen yourself.
