The only suffering one experiences is the suffering that they allow.
One is in control of how they react to any situation, as well as how they react to their own thoughts. We all have the ability to observe and change our own reactive patterns. These reactive patterns are often linked to some type of emotion, which can sometimes cause one suffering (although not always!).
By changing the way one reacts, one can stop allowing thoughts and situations to have power over their emotions.
Don’t believe everything you think.
Sometimes people can be so used to repetitive negative thoughts and identifying with thought that they begin to truly believe certain negative thoughts to be true, when in reality, they have nothing to do with the Truth.
Once one becomes aware of thought, they then have the power to recognize what thoughts bring them suffering versus what thoughts bring them inner peace. Once one makes this connection, they can then let go of the thoughts that induce nothing but negativity, and focus more of their attention and awareness on their positive thoughts.
One can try letting go of what no longer grows them, serves them, or makes them happy.
