I would also say that absent-mindedness is a concept/thought (with its own sphere), mindfulness is another, adopting the sphere of thought of concentration and mindfulness would avoid absent-mindedness.
Anandamoy talked about 'the vast spheres of thought of God's creation'. Hence we must presume there are regions of thoughts, or vast sets or clusters of thought, similar one to another, yet not identical, part of the same ensemble of concepts.
Yes, like ‘radio waves’ and ‘different frequencies’ , at times we can pick up on the different wavelengths from others around us and attune our selves to their sphere of thought, just by a few words, a look or body language.
I still remember bringing my mother to listen to a speaker at the LAKE SHRINE, it was decades ago when Brother was still alive. Brother Anandamoy was speaking that morning. When we left he blessed us, which was typical at a small gathering in those days. My mother was very intuitive about people and as we walked to the car she said to me….
“That man is so handsome.” But then she said; “And he knew what I was thinking. He could read my mind.” Well I wasn’t so sure how to respond, but was happy she had occasion to meet him and listen to the lecture he gave that beautiful Sunday morning in the Windmill Chapel at the Lake Shrine. She apparently had some type of connection with him when he blessed her. She was surprisingly open and honest about her experience that morning. In fact I do not ever recall her ever telling me anything so intimate about another man except perhaps my father.
