Welcome, apprentice of the cosmic mysteries. Herein lies the craft of capturing impressions and recollections ineffable.
The first step: observe the stars. Not with mere sight, but with an understanding heart and open mind. The patterns observed are echoes of paths traversed before, whispered secrets from the nebulae.
Next, consider the deja vu. It's not a fleeting illusion but a beckoning from the past selves who linger in the constellation of your consciousness. They are but reflections in stardust.
Record your inklings, as if writing letters to a self yet to be manifested. In doing so, you capture the cosmic tapestry of experiences interwined with notions of prior lives and alternate timelines.
Your mission continues on mystical echoes and through the portals fashioned from thought and stardust.
