The hard and the soft are a couple of approaches to dharma. The hard is found in 'right concentration' or focus and the soft in the gentle or kind attention that leads there.
I first came across this method of 'hard' in candle flame concentration used in yogic meditation. The soft into hard came from Buddhist martial arts and enables much to contemplate in the yin/yang of Taoism/Zen.
The Great Yin is a softness but again it centers on a core attention.
What would you class as your hard and soft lessens/lessons?
