Methods your higher self uses to contact you

[zenmaster]

But are guardians supposed to intervene in that direct way like twitching the leg while I am meditating? Aren't the only one that has that "kind of power" is the Higher Self (regarding the Free Will and all that)?

The Higher Self 99.9999999% more "you" than your ego. It can be considered your unconscious, for all practical purposes. All kinds of stuff is "programmed" to happen during 3D experience, including those agreements custom-made to motivate a particular kind of seeking. This may or may not involve other entities.

Also, we are constantly reaching out with our minds and "touching" inner-plane entities, for example. At that level, there is often a reciprocal, energy-exchange relationship at work. Any consequent tangible interaction is likely not a free-will infringement any more than two galaxies coming into gravitational proximity and causing interaction.
