A candle flame heats the air surrounding it. Hot air, being less dense or lighter, rises. To take its place, surrounding heavier or dense cold air rushes in. It also in turn gets heated and rises. This continuous cycle of hot air rising, cold air rushing in, getting heated, causes a swirling effect, thus making the flame always point upward.
