Someone asked: why has life changed so quickly after only a short time of meditating?

Just Three Hours Can Reveal Wonders, If the Mind Abides in Wholesomeness

Seeing wonders in one's life after only three hours of sitting shows that the mind is already quite wholesome — abiding in the wholesome system for even a short while can bear fruit. But three hours alone isn't enough, because for the rest of the day we remain surrounded by other conditions that may belong to the unwholesome side.

Extending Time Within the Wholesome System

We need to use whatever time we have to train the mind to abide in wholesomeness as continuously as possible. Otherwise, the mind falls back into other systems, and our disposition shifts according to that other nature. Back when we were part of the special merit lineage in the Tusita heaven, our minds abided in wholesomeness day and night without interruption. Having come down to be born as humans, that disposition must be carried forward and maintained — and if it wasn't carried over, it must be rebuilt through practice, because if we fail to establish it in this life, the next life becomes even harder.

Mindfulness Paired with Ease: Letting the Wholesome Take Over

This training isn't difficult. Simply bring body and mind to sit. At first there may be little inclination to sit, since impurity is still considerable, but after sitting for a while, the wholesome side takes over and handles the rest. Luang Phor taught 'mindfulness paired with ease' — sit with the body and mind at ease, then observe the results: knowledge together with happiness and purity, the very qualities of the merit-element flowing through us. As merit flows through, we come to recognize the happiness and purity that arise, and life develops further, letting us sit for many hours at a time — even across days and nights — as the wholesome side supplies tools such as spheres of light, spheres of Dhamma, or the Buddha image itself, to help sustain longer and longer periods of sitting.
