As there is no way of breaking the causal chain, there is fate. There is only one path, and we can call it fate. But, if there is only fate, and nothing outside of it, the idea behind the word "fate" losses its meaning. There is only whole and perfect reality and we are always in it.
As I see it, it is not the same as karma. Karma is accumulated when we, by thinking the there are many paths, build up preferences toward one of them. In other words, karma comes from expectations, and hits back when those are not fulfilled. So karma is caused by ignorance, and assumption that there is something more the fate, which is impossible, as fate is everything in sameness.
