The goma service performed outdoors is referred to as the Saito goma, with the Shingon sect line Tozan school using the kanji meaning 'firewood light' for 'Saito' as it was impossible to decorate the esoteric tools such as Buddha statues and temples in a formal manner in the mountains where they built the gomadan with firewood or logs, whereas the Tendai sect line Honzan school uses the kanji meaning 'receiving the light' as that school acquires light from the saito of the Shingon sect line Tozan school to perform the goma.
野外において修される護摩法要を、柴燈・採燈（灯）（さいとう）護摩というが、真言系当山派では、山中で正式な密具の荘厳もままならず、柴や薪で檀を築いたので「柴燈」とし、天台系本山派では、真言当山派の柴燈から採火して護摩を修するようになったので「採燈」という。
