Samadhi means concentration - like Heinz concentrated soup. One way to understand Dharma is to concentrate your soup. In your soup there are many ingredients - not just wholesome vegetables like leek and potato. There are also spices called greed, hate and delusion of many kinds. Some like it hot. This concentrated mass of goo is the homeless home, the ever seething cauldron of real life.
Mostly people are trying to dilute, bury or unsoup their soup. Diluting means trying to become pure water. There are lots of wet people wandering around in spiritual centres competing in the race to have the thinnest soup. Yet adding water does not remove the goo - it just spreads it out and makes it thinner so that it ends up making everywhere sticky. This stickiness is called false holiness.
