Several animals species have developed (Nature!) internal original natural GPS system that assist them in migrating outstanding distances (by land, air or water) across the globe.

They do this for the same reason as their human counterparts, for "greener pastures". And, humans too have been on the move across the planet since our times in the first cave dwellings.

 "Migration is our history, psychic migration not the physical movement of bodies." So true! Our main purpose for InSelf Yoga is to migrate to better and higher realms that will be conducive to continued practice. All other religions practices also advocate relocation to paradisiac environments, in the hereafter.

Reaching for improved conditions or better positions seems to be an essential component of any psyche, including plant life form’s. But humans at times miscalculate the possibilities/ opportunities for prosperous locations, and can have their plans turned up side down.

That happens here-now, and also hereafter! Once there, it does happen that one realizes that their aspirations (projections and hopes) are totally missed. And the search/ hankering continue for evermore.
