In the West we are not used to knowing the mind like this. We know, intellectually and scientifically, that the brain is plastic. Plastic, or plasticity, is a contemporary word that signifies the possibility of the descriptors of mind above.
A mind that is malleable, wieldy, pliable, and steady is capable of real transformation. If you become serious about your personal meditation practice, if you give the mind time and opportunity to develop concentration, you can realize this potential.
You might keep in mind that, "this flexibility of mind is not impossible to attain, it is another thing to maintain." (quoting myself in Practice Board entry)
A course or two, even sitting every day, does not yield an ongoing transformational process. A course and a regular sitting are a good start. But a significant evolution of mind involves a steady and committed practice, a process that is usually gradual and organic, but includes dedicated time for fostering a concentrated mind. With support the mind discovers these truths.
Periodic teacher input will save you from invisible roadblocks and circuitous side tracks.
The teachings I offer are all intended to help as many people as possible realize this potential. The most immediate and accessible opportunity is a non-residential retreat for both new and experienced meditators in Houston August 19 and 20 http://www.citta101.com/retreats.htm
