Some writings says like that:
"After any chakra practice, it is VERY important to close them unless you still want to use them as during the projection.
This closure is especially important if we FEEL the strong activity in them. If the chakras remain open during our normal daily activities, our energy will drain. This can cause fatigue and possibly health problems. You may inadvertently draw the attention of unwanted astral beings."
Did we really need to "close" our chakras after energy meditations?
