I must admit I do not really understand "playing by feel" idea

Does it mean you ignore poker math? For me poker is all about math and statistics. "Felling" could be only to decide if the opponent bluffs or should I
bluff in some spots. But choosing bluffs to spot is still to be decided by some reasoning, not emotions. If I am to decide if someone bluffs I also try to consider his playing style, things he did in the past if I have any data, the board texture, the opponent previous bids and their posssible cards, my cards and EV etc.. Well, it doesn't sound like "by feel" at all
