Guru goes into debilitation, ie the sign of capricorn or makara, once in every 12 years.
when guru goes into debilitation if mars/kuja(the planet which gets exalted in makara/capricorn) or sani/saturn(the owner of the sign makara) chances to occupy a kendra/angle(1, 4, 7, 10 houses) from lagna/ascendant or chandra/moon, it becomes a rajayoga called chakravarthi yoga. (instead of guru, if any other planet goes into debilitation, similar rules can be applied)
chakravarthi yoga or neechabhanga rajayoga means, after a person gets a neecha/fall he rises into a position of prominence.
if mars is the planet responsible, then it is physical activity(aggressive action) that will trigger his growth and if it is sani/saturn, it will be contemplation and politically correct decision making.
mars is activity while saturn is stillness.
mars needs lot of disciplined physical exercising while saturn needs breathing discipline like pranayama.
