For example, in the RHP, you MUST comply with specific moral, or at least behavioural, criteria laid down by an EXTERNAL moral authority, be it God, Parasiva/Parasakti, karma, traditional taboos, “the highest good of all” or whatever.
This model also holds that the human soul is (variously) fallen, incomplete, in dire need of evolution, or simply impure and wrongfully attached to the world of the flesh.
And that the adherent’s primary aspiration must be to comply with the guidelines given, in order to become saved, whole, pure, and detached from worldly concerns.
In the LHP, you have no moral or behavioural constraints, no outside “judge” awarding you a desired spiritual state (whether after death or beforehand) such as enlightenment, heaven, or Nirvana, and there’s no other state to aspire to except that which you desire for yourself, although for many of us who’ve bothered going this far, that will amount to becoming the primary creative force in our own spacetime perception (universe, reality, call it what you will).
With - let me repeat this before anyone says, “But dear silly Eva, we all create our own reality anyway” - no moral or behavioural strictures whatsoever.
How these two things can be alike - how there can be a “middle path” that has a bit of both, honestly escapes me, since the whole idea of RHP is to evolve spiritually along a path determined by external laws and rules, whereas the whole idea of the LHP is to dispense with these.
