“純淨的感覺”“維持“良好狀態”

It is most difficult to climb up and reach the highest mountain peak; but even more difficult to remain steady on the peak because there is greater danger of falling from the height.
Similarly, it is very difficult to reach a ‘good state’ in meditation and even more difficult to maintain the state one has achieved. It can only be maintained through ‘pure feeling’

要攀爬並達到頂峰是很困難的；但是要穩定的維持在頂峰是更困難，因爲從高處跌下來的風險更大。

同樣的，要在靜心時達到“良好狀態”很困難，但要保持所達到的狀態甚至更難。只有透過“純淨的感覺”才能維持。
