We are feeling creatures. Our feelings frame our reality. What we believe to be true is what we feel to be true. We accept facts or dismiss them based on how we feel about them.
We assign value to words based on how we feel about them, and then assign value to people based on those words.
So to change our reality, we must learn how to reorient ourselves. Change how we feel about the world, so that we change the view we have about the universe. We can learn how to no longer assign internal values to words and people so that we can see and accept them as they are.
If it is too challenging to do this spiritual shift through your own meditation and introspection, then transform your spirit through your actions. Because we are not body and mind but one body-mind (psycho-physical) being. How we behave effects our minds just as much as how our minds effect how we behave.
So while many Buddhist practitioners focus on meditation as the path to understanding suffering, we can assist those who wish to follow the dharma by developing other aspects of their practice: charity, volunteering, service to the temple, socratic dialogue, etc.
It is nearly impossible to develop a meditative practice in Buddhism without developing some sense of anicca and anatta, which leads to opening the doors to embodying metta, karuna, muditta and uppekka. By developing metta, karuna, muditta and uppekka through ADLs (activities of daily living) will eventually open the mind’s door to the gentleness of a meditative mind which understands anicca and anatta.
