Why you feel reality is so concrete,sort of dense?remember the nature of mind is clean clear light,not only the positive but also the negative they both are unified in the space of clarity.Clean clear mind,the nature is like this clean clear both in sutra and tantra they say,don’t go into judgemental speculation that are just conceptions and elaborations,stay on the clarity nature of your own mind then eventually you will discover, unveil the courtain,that’s all.
