will doing void meditation stop me from practising my goal or getting any good thoughts of aim,fame,success or will it totally only stop intrusive thoughts?
The purpose of void meditation is to learn to control your mind. Being able to control your mind is a very important skill and will help achieving other goals.
"Void Meditation is what is known as "stilling the mind." The benefits of void meditation are the ability to turn off unwanted thoughts and influences at will, being able to control your thoughts instead of your thoughts controlling you (as with the average person), and a sense of inner peace."
