You walk alone. This is a path nobody but you can take. You inhale and start getting closer, one step at a time. The light can be blinding, but you're sure it's not gonna hurt you. Pain is a concept unfamiliar to you in this state of being.
You feel the light slowly bathing your every atom. You can tell you're not the first one to walk this path, as there's footsteps ahead.
Behind you there is only darkness, the nothingness itself lurking after you, waiting for you to make a wrong move, to fall, to lose concentration. You focus on the road ahead; your only objective, reaching the other side.
You feel tingles all over your body. You feel weightless. You push harder.
The light is so overwhelming that nothing else seems to exist, only light surrounding you, welcoming you to what's beyond the portal.
You cross the portal.
