Successive thoughts do not stop; prior thoughts, present thoughts, and future thoughts follow one after the other without cessation. If one instant of thought is cut off, the Dharma body separates from the physical body, and in the midst of successive thoughts there will be no place for attachment to anything. If one instant of thought clings, then successive thoughts cling; this is known as being fettered. If in all things successive thoughts do not cling, then you are unfettered. There- fore, non-abiding is made the basis.
Interesting quotes. Here's a few thoughts...
If I say to myself that I need to solve this problem I face, and I must figure this out, then there's a tendency to cling to each subsequent thought as being necessary to finding peace and happiness. If instead I can 'let go' of the problem and just perform a simple action while in a mindful state of calm abiding, and can peacefully do work without 'stressing' about it.
Its enough to drive yourself crazy when thinking obsessively about something that's upsetting that happens. There's any number of things that could happen at any given moment. Say your girlfriend or boyfriend dumps you.... or during an ice storm a tree fell on your car.... you or a loved one is diagnosed with a serious illness...
So what do you do? Does obsessing about it endlessly achieve anything positive? Worrying only begets more worrying and results in an unhappy tired feeling. Buddhism teaches to seek liberation from this by practise meditation (right concentration) and living according to the Noble Eightfold Path.
To be unstained in all environments is called no-thought. If on the basis of your own thoughts you separate from environment, then, in regard to things, thoughts are not produced. If you stop thinking of the myriad things, and cast aside all thoughts, as soon as one instant of thought is cut off, you will be reborn in another realm.
If I believe that my job is everything to me (many people live for their career) I would likely become very upset if I were to learn that the company was downsizing or laying off (this has been happening very frequently for the past 5 years).
If I believe that my car is everything to me (many people are very serious about their car) I would likely become very unhappy and upset if it was damaged somehow (and car accidents happen very frequently!).
If I learn I am not defined by my environment then I am liberated and anything is possible for me.
But if I believe that I am defined by my environment, I might grow up to believe that "I'm poor" because I grew up in a ghetto. I might grow to hate wealth or wealthy people etc.
