Sometimes it is easy, sometimes it is hard, im not sure if the ease of stilling or calming the mind (not pure stillness, just mostly still) is related to mindfulness or dwelling in pure awareness throughout the day. All i can concur is when the mind is still experiences arise, which i have learnt to call jhana, maybe it would be better to say that when the mind is calm experiences arise (1st) and when it is still that is more 2nd jhana. I can't speak further than that as i have not been further.
The music of the spheres that you talk about in the video Jeffrey is that the auditory charism? Because that is something that seems to be present with me mostly all the time, always as a high pitched tone, often with another lower pitched tone present as well, sometimes as many as 3 different tones all going off at the same time. Often i get a random ringing in the "ear" but it's more from no source it's kind of everywhere, and it can come in pulses like Beep, beep, beep, beep, beep. Sort of random, haven't had that before the other day hah.
