From his third autobiography: “If there is a state where the soul can find a resting-place secure enough to establish itself and concentrate its entire being there, with no need to remember the past or reach into the future, where time is nothing to it, … [with] no other feeling of deprivation or enjoyment, pleasure or pain, desire or fear than the simple feeling of existence, … as long as this state lasts, we can call ourselves happy.” (Sounds like mindfulness to us …)
