Do not follow the smoke up but rather allow the smoke to forms patterns within your spiritual gaze. In time you will see visions of many far off events.
I have generally found people who have natural artistic skill good at this form of scrying.
The American Indians practise a special type of smoke scrying. It's called a sweat lodge.
Water is poured over hot rocks in a tent to create steam. The steam is inhaled by those who sit naked around the rocks.
The combination of temperature, humidity and elevated levels of carbon dioxide produce a state in which visions can arise. This form of scrying may be dangerous and should only be undertaken by experienced people.
