I do know how semantic change works, yes. And your pudding example shows that borrowing (and phonological adaptation) is likely beside the point. Words can change their meaning (and generally do) even when speakers are staying in the same geographic location (e.g. Sanskrit lokaḥ "world" became the Hindi plural marker log). But all of this seems somewhat irrelevant to me for the topic at hand. Buddhism has a long history in India before reaching China, including meditative/concentration. Obviously there were significant developments in China (and Japan) which make Zen Buddhism distinct, but it seems odd to ignore the Indian Buddhist base it's built upon.
