I am Ajay.
My humble pranams and well-wishes to all of you here.
Quoted above are a list of teachings of various masters which I compiled myself for a better understanding and contemplation of the message of proactivity and reactivity.
Through study and analysis of the master's teachings, I had come to the understanding that it is proactive action which is what is known as virtue or good karma while reactive action is what is known as sin or bad karma.
While proactivity is what stems from a state of awareness or mindfulness , reactivity on the other hand stems from the ego .
Living in the present moment generates awareness, while living in the past or future due to desires, craving or incessant thinking is what generates the ego.
The state of awareness generates happiness , while the ego generates pain and sorrow.
This is why the Buddha had said thus ," Mindfulness ( constant awareness ) is the only true virtue."
And why Eckhart Tolle had stated thus. " Evil is an extreme manifestation of human unconsciousness."
Writing this in my notebook and constant study and contemplation of these teachings from time to time helped me to become a more self-aware, proactive and less reactive person. This understanding brought a deep sense of calmness, peace, contentment and well-being in my life.
Hope the reading of the above mentioned teachings will do the same for you or help in bringing perspective on the nature of the mind.
