Seeing the solar system built to scale put into perspective just how minuscule we are in relation to the universe. Realistically, our physical and materialist gains are insignificant and transitory. Non-spiritual achievements are simply not worthy of our toil, struggle, and attachment.
There are a myriad of means to facilitate the study and practice of the Dharma. It is vital to not be caught in the whirlwind of the concrete words and the varied conveyance methods. It is critical to not let the concrete agent distract from the transmission of The Teaching.--ZenMoon
