When soul comes on the ground, it stays until all souls are down, by that time all souls are so impure that an external source (God) has to intervene and purify them and bring their energy back to the highest ordered state.
God has come down already as you see so many centers , ashrams, people learning yoga and meditation etc.
Less resources, less food, people start cheating, stealing etc more population as souls do not go back until the whole drama ends.
We are either at the ending period going through Kalyug or at the start of the satyug.
called Diamond age ( Sangum yug) where the souls would meet God. This is a beautiful time for
all souls.
We are at the 11th hour of the era or going through Diamond age where souls meet God and will be taking us to the Golden age. This is a beautiful time when God will take souls to the pure state by energizing them. Lots of cleaning (flooding, earthquakes)is going on right now, some souls will make it to the other side by themselves as they are on a good path, some would need help as they have their karmic debts to pay, they would be struggling and some will not survive as God would take them, clean them and then will come down when it is their time.
Start preparation for the morning or Golden age, do meditation so you have to suffer less and you are ready to cross the line to the Golden age.
