Does anyone know what does it mean to be concentrated at the third eye,the brow chakra or tisra til?I mean does it mean for example to close the eyes lovingly-intently just as in sleep and then look at the darkness that lies in front of someone or close the eyes and do nothing or close the eyes and try feeling that they are in the darkness or close the eyes and try to visualize the center of the head(brain) or what?Write down please whatever you know what does that mean…I will be waiting for your answers 😉
