Steve, I cannot say I understood perfectly.
I often do not understand what I’m reading or what someone is saying. Although in these cases the responsibility does not all lie with our inability to understand but also in the inability of others to express themselves clearly.
Time is seemingly indelible in its slow unfolding progression in this dense reality. We are constantly at its mercy and unable to manifest things quickly enough for our satisfaction. Thus we have to have to adapt to the mentor of time or let go of our desire to have things manifest according to our dictate, desire and expectations. Which ( our dictate and desire ) in essence is just one more form of ego ( our expectations) manifesting. In astrology the Lord of time is Saturn 🪐. It is the planet that metes out our karma thru the progression of time in the medium of space.
OK, clearer now. Time is definitely a constraint, a fair one though since it applies to everyone, regardless of all other things. Space-time may be in part manipulated by wealth, for example by fast transport vehicles that wealthy people can afford. Pure time is un-stretchable though, at the non-relativistic speeds which can be reached nowadays. Our management of time is of supreme importance. We must learn to optimize everything.
