It’s a dangerous way of talking about consciousness which is constantly explained to be dependently arisen.
There are many instances of fire being lit in dependence on many things in the world, a log-fire here, there a grass-fire, over there an oil-lamp.
To speak of a consciousness jumping around is essential akin to speaking of a fire jumping from one place to another.
Suppose i light & put out a log-fire on a monday and i light a grass-fire on a tuesday. You wouldn’t say that the fire having landed on the logs jumped to the grass.
Why is that? Because clearly it is not the same fire!
The fire that was on monday had ceased by the time i light the grass-fire.
In exactly the same way it is taught that this or that consciousness originates due to conditions. You may discern eye-consciousness
and later discern ear-consciousness but no consciousness jumped from the eye to the ear.
The consciousness that arose in dependence on the ear ceased by the time that ear-consciousness arose. There is no jumping of a thing from one to another.
Suppose i use friction to light a small grass-fire, having lit a grass fire i would light a candle and with this lit candle i would light a grass-torch which would later be extinguished.
You wouldn’t say that i summoned a fiery monster by performing the ritual of rubbing a stick, a monster which then jumped from the grass and onto the candle before jumping onto a light-torch to feed on the grass.
In the same way you shouldn’t make a mental monster which roams around, jumping from here to there out of consciousness.
There are communicable conventions. For example suppose you light a small fire for cooking near a farmers corn field.
Then you would make mediocre effort to extinguish it half-heartedly and walk away, leaving hot coals.
Then a wind would blow and the fire would blaze up again due to your negligence in putting it out. Then somehow the fire would spread to light up the corn-field.
Now here are two ways of thinking about it.
- You didn’t set the corn field on fire.
- You did set the corn field on fire.
Obviously the farmer would blame you saying that the fire you lit had spread to the field even if it’s obviously not the same fire and you had no intention of setting the field on fire.
Nothing therein actually jumped from one thing to another. The flame that you had put out was extinguished and another flame arose due to the wind’s blowing.
It’s not like you had summoned a fiery monster which hid from you in the coals before jumping out and onto the field.
It is not one and the same fire jumping from one thing to another.
Likewise there is no such thing as a single consciousness-entity roaming & jumping around. Past consciousness ‘was’, has been, and the future consciousness is not yet begotten, these are not the same thing.
