No , it still doesn't. What you are suggesting can also be achieved via antinatalism as well instead of meditation.
No you can't achieve this via anti-natalism. Even if all humans collectively agreed not to reproduce, you can't stop animals and plants and other life forms to stop reproducing. My religion says that you can take re-birth as any life form. If not human then maybe a salmon fish. and it is literally impossible to stop every human on planet to collectively stop from reproducing. Its a BullSh idea.
Lets assume u manage to stop every life form on earth to reproduce. Hinduism says that there is a never ending multiverse, filled with infinite universes. Each universe filled with quadrillion different life forms. So if u stop every life form on earth to reproduce, you will simply get reborn on another planet far away from earth.
My question was how to free oneself from suffering in this birth , when you are already here.
Again I will repeat myself. IF YOU ARE BORN IN THIS MATERIALISTIC MATRIX, YOU WILL HAVE TO SUFFER. Being born is a suffering itself.
The breaking of cycle (if it were true) will impact the next cycle.
If the cycle of "your" birth and death breaks that means u have attained liberation (moksha). Now are one with the universe. Just like pouring one glass of water into the Pacific ocean. It won't impact anything. Your consciousness will simply become one with that of the universe. IT WON'T AFFECT / IMPACT ANY OTHER OR NEXT CYCLE.
If I get access to painless exit , I get to control my suffering. Even if I come to this world a thousand times (considering such a cycle exists) , I can exit whenever my pain reaches a threshold.
So u will have to repeat this infinite times. You will keep deteriorating in the materialistic realm forever within the cycle of life and death. It the worst situation you can get yourself into.
I don't have to subject myself to harsh conditions of Himalayan temperatures , no food , no shelter etc to resist suffering.
Every time you get birth YOU WILL BE SUBJECTED TO HARSH CONDITIONS. I wish not, but what if you got birth as a lab rat in some research lab!! Or were born as an insect in China. Or as a human in a war zone. You will have to face harsh environments.
For liberation its not necessary that you have to meditate in harsh environments. There multiple methods by which you can attain liberation. The sages and saints in Himalayas chose the harsh method by their choice.
But I never understood what started this cycle? Do you have any idea on that
That's a really great question. I know the fundamental idea behind the actual answer of this question. I haven't read enough books and scriptures to answer this question properly. I have very limited knowledge about it.
