Hello. I'm he same as Xerzel. I concentrate on that person and I'm there but in my opinion , you have to be able to calm your mind to obtain this. I meditate a lot and I think the practice of calming my mind has help me to get quick results to my questions. But that's just me. You can focus more quickly on someone or something. It took me a while to set and meditate on "nothing " No past or future. No colors or visions. Only on stillness. But that's just my opinion and how I have achieved a clearer vision and knowing.
