​Can a witch light a candle with her mind and control the fire?

I think you are confusing witchcraft with the power of telekinesis here which is employing thought waves to move physical objects. It’s a debated point whether this is a natural gift or something that could be achieved over time with proficient and focused meditation. There is certainly documented scientific evidence to support the fact that telekinesis exists but it is interesting to note that the subjects do not self identify as witches or magical practitioners.

I wouldn’t rule out the possibility that a witch skilled in projecting intent and focusing her mind might be able to light a candle in this manner. What I would question however is why any witch would want to do it…  The whole point of witchcraft is that magic and power are employed for practical and necessary purposes. To go to all that effort to achieve something a task mentally that could be very easily performed by buying a box of matches seems to me to fly in the face of what any reasonable witch wants to get out of her craft.

Simply put:
Most can’t. Those who could wouldn’t bother because there is no value in developing this skill.
