quenching the spirit

Reading Brengle's book "When the Holy Ghost is come" gave me some new insight into what it means when the bible is warning us not to "quench the Spirit". Ever thought about that?
What about this explanation? Makes me at times be pretty close to what is so fatal to our walk with God.

"You do not need to do some great evil, some deadly sin, to quench the Spirit. Just cease to rejoice, thorugh fear of man and of being peculiar; be prim and proper as a white and polished gravestone; let gushing joy be curbed; neglect to pray when you feel a gentle pull in your heart to get alone with the Lord; omit giving hearty thanks for all God’s tender mercies, faithful discipline and loving chastenings, and soon you will find the Spirit quenched. He will no longer spring up joyously like a well of living water within you. "
