guys do you believe in soulmates?Watch
If it means some mystical, spiritual connection BS, we-were-meant-to-be-together, no, obvs.
Spirituality is, that humans could be improved from within, by correcting their thoughts and discovering knowledge already there since birth. All humans are already born with Innate knowledge or Inborn knowledge, we just have to focus on reasoning and find out what innate knowledge do we have. Since innate/inborn knowledge exists, this also proves that humans are born with some sort of essence which again we have to find out through reasoning and different practical experiences.
And since all humans have an essence, we also have pre-determined (determinism and free-will exist together) stuff.
Existence of mind, proves existence of spirituality.
Existence of spirituality proves existence of Inborn knowledge.
Existence of Inborn knowledge proves existence of essence.
Existences of essence proves, existences of many pre-determined stuff (events, illness, sustenance etc.)
So the answer is yes, humans do have a soulmate.
