To gather aura in the Sahasrara chakra, you need to focus your meditation on the space between your eyebrows, and that will lead you to a state of stillness. However, I often felt like I was stuck at the Sahasrara chakra, as if there was a wall above it.

It felt like a state of stillness that wasn't completely pure, almost silent, but something was missing.

At that time, the aura in the Sahasrara chakra would sometimes be full and sometimes not, and it varied from day to day. I think I was meditating by focusing on the space between my eyebrows, and sometimes, unexpectedly, the aura would fill the Sahasrara chakra, leading me to a state of stillness.

Now, it's relatively easy to raise the aura, but sometimes I still feel like there's a wall above the Sahasrara chakra.

Previously, when I was in that state, I often couldn't progress any further. Some days there was a wall, and other days there wasn't, and I wondered what the difference was.

At that time, I sometimes tried chanting "Om" or other mantras, but sometimes it worked and sometimes it didn't, and there wasn't a particularly effective method.

Recently, I started meditating by simply expressing gratitude, and I suddenly realized that this "wall" above the Sahasrara chakra can be overcome very quickly by expressing gratitude.

Just now, I meditated, and I rarely felt that wall again, like in the old days. I thought, "I haven't felt this sensation recently," and I tried saying "Thank you" in my heart, without directing it to anyone in particular, towards the space around me. Although this wasn't specifically aimed at the Sahasrara chakra, I felt that the words of gratitude were particularly effective for this "wall," and suddenly, the aura spread out around my head, as if there was no wall at all. The wall quickly dissipated, and it felt like there was no wall.

The effect of gratitude is also seen in such places.

There are mantras like "Om," and many others, but I've recently realized that the words "Thank you" are quite powerful, and they might even be a substitute for mantras.
