Ama-decan e-astrology angenye yezindlela zakudala zokwengeza imininingwane ezimpawini eziyishumi nambili ze-zodiac. Uphawu ngalunye luhlukaniswa lube izingxenye ezintathu zamadigri ayishumi, kwakheke izifunda ezincane ezingu-36. Eshadini lokuzalwa, i-decan yeplanethi ingachaza kabanzi indlela amandla ophawu abonakala ngayo. Ayithathi indawo yophawu, indlu noma ama-aspect; kunalokho, yengeza ungqimba lwesibili olwenza indawo ethile iqondakale ngokuningiliziwe.
Igama elithi decan lisuselwa egameni lesiGreki elihlobene neqembu lezinto eziyishumi. Lo mbono unezimpande endleleni yasendulo yaseGibhithe yokubala isikhathi. Amaqembu ezinkanyezi angu-36 ayesiza ukumaka amahora obusuku phakathi nonyaka. Njengoba i-astrology ikhula ngaphansi kwamasiko aseGibhithe, eBhabhiloni naseHellenistic, lezi zigaba zaqala ukuhlotshaniswa ne-zodiac. Umlando wazo ukhombisa umzamo omude wokuhlela isibhakabhaka sibe imijikelezo enencazelo namaphethini aphindaphindayo.
Kulula ukuthola i-decan. U-Aries uthatha amadigri angu-0 kuya ku-29 e-zodiac. Ngakho-ke, i-decan yokuqala ka-Aries isuka ku-0 kuya ku-9 degrees, eyesibili isuka ku-10 kuya ku-19, kanti eyesithathu isuka ku-20 kuya ku-29. Isakhiwo esifanayo sisebenza kuzo zonke izimpawu. Iplanethi eku-4 degrees eTaurus ikwi-decan yokuqala yeTaurus, kanti ekwi-23 degrees eTaurus ikweyesithathu.
Kunezindlela eziningana zokunikeza ama-decan ababusi bamaplanethi. Indlela esetshenziswa kakhulu ezikhathini zanamuhla ibizwa ngokuthi ama-Chaldean decans. Inikeza amaplanethi ngokulandelana okuphindaphindayo, iqale ngo-Mars ku-decan yokuqala ka-Aries. Ngale ndlela, uphawu ngalunye lunababusi abathathu bama-decan. Ukulandelana kuhamba ngendlela ethile yamaplanethi, kunokuba kuphindaphinde nje umbusi wendabuko wophawu.
Enye indlela esetshenziswa kakhulu, ikakhulukazi ku-astrology yanamuhla, ihlobanisa ama-decan ento ngayinye nezimpawu ezintathu ezinaleyo nto efanayo. I-decan yokuqala ihlotshaniswa nophawu uqobo, eyesibili nophawu olulandelayo lwaleyo nto, eyesithathu nophawu lokugcina. Ngokwesibonelo, izimpawu zomlilo zingahlelwa kanje: u-Aries, u-Leo no-Sagittarius. Le ndlela yakha ubudlelwano obucacile phakathi kwezimpawu ezintathu ezabelana ngento efanayo.
Njengoba lezi zinhlelo zinikeza imiphumela ehlukene, kubalulekile ukucacisa ukuthi iyiphi esetshenziswayo. Incazelo iba nokudideka uma ababusi bamaplanethi bohlelo olulodwa behlanganiswa ngokunganaki nezincazelo zolunye. Akudingekile ukubheka uhlelo olulodwa njengolusebenza kuwo wonke umuntu. Okubalulekile ukukhetha uhlaka olungaguquki, uqonde umlando walo bese ulusebenzisa ngokulinganisela.
Ukuze ufunde i-decan eshadini lokuzalwa, qala ngeplanethi nangophawu olukuyo. IVenus eseGemini isalokhu iyiVenus eseGemini; ukuxhumana, ilukuluku, ukuhlukahluka nokuxhumana kwengqondo kuseyizindikimba eziyinhloko. I-decan ingangeza umehluko omncane endleleni la mandla azwakala ngayo. Uma uVenus ekwi-decan yesibili, isazi se-astrology esisebenzisa indlela yezinto singase sihlanganise ithonya lika-Libra, sigcizelele ubumnene emphakathini, ukulinganisela nokubambisana. Lokhu akudali uphawu olusha. Kunalokho, kuchaza ngokuningiliziwe indlela uVenus eseGemini angafuna ngayo ukusondelana nabanye.
Le ndlela ingasetshenziswa naku-Ascendant, iLanga, iNyanga nombusi weshadi, nakuba kungeyona yonke indawo okufanele inikwe ukunakwa okufanayo. Qala ngamaphuzu eshadi ahlela okuhlangenwe nakho okuyinhloko komuntu. I-Ascendant ichaza indlela umuntu ahlangana ngayo nokuphila, iLanga lihlobene namandla nokuziveza ngenhloso, kanti iNyanga lichaza amaphethini emizwa nezimpendulo ezijwayelekile. I-decan ingasiza ukuhlukanisa abantu ababili abanendawo enkulu efanayo yophawu, kodwa kufanele ihlale ingaphansi kwencazelo yeshadi lonke.
Imingcele yamadigri idinga ukunakwa. Uma iplanethi iseduze kuka-10 noma 20 degrees, hlola idigri eliqondile kanye nomkhuba osetshenziswa uhlelo lwekhompyutha olwakha ishadi. Ukusondeza inombolo kungasusa iplanethi kwenye i-decan iyise kwenye. Kuhle futhi ukugwema ukunikeza i-decan incazelo ebanzi uma isikhathi sokuzalwa singaqinisekile, ngoba indawo yeplanethi uqobo ingase inganembi.
Ama-decan angasiza kakhulu lapho kuqhathaniswa amashadi. Abantu ababili bangaba noMercury eVirgo, kodwa uMercury womunye abe ku-decan yokuqala kanti owomunye ube kweyesithathu. Bobabili bangathanda ukuhlaziya nokunemba, kodwa lokho kungaziveza ngezindlela ezahlukene. Omunye angagxila emaqinisweni asheshayo nasekuhleleni okusebenzayo, kanti omunye angakhuluma ngendlela ebanzi, ehlelekile noma egxile ebudlelwaneni, kuye ngohlelo lwe-decan olukhethiwe. Lokhu akubikezeli ukuhambisana kwabantu. Kungeza nje omunye umbuzo ongacutshungulwa ekuqhathaniseni.
Umsebenzi olula wokuqonda ama-decan ukukhetha iplanethi eyinhloko bese ubhala izigaba ezintathu zencazelo. Okokuqala, chaza umsebenzi oyisisekelo weplanethi. Okwesibili, chaza indlela uphawu oluwubumba ngayo lowo msebenzi. Okwesithathu, engeza i-decan njengendlela engenzeka yokubonakala noma ukugcizelela. Bese uqhathanisa lokho nendlu nama-aspect. Uma incazelo ye-decan ingahambisani nezinto ezinamandla kakhulu eshadini, vumela lezo zinto ezinamandla zihole.
Ama-decan abaluleke kakhulu uma esetshenziswa njengolimi lokuhlukanisa umehluko, hhayi njengendlela emfushane yokuchaza umuntu. Agcina isakhiwo esibanzi se-zodiac, kodwa aqaphele ukuthi amadigri ayishumi ophawu angazwakala ehlukile kwamanye amadigri ayishumi. Uma uwafunda wazi umlando wawo futhi ungawasebenzisi ngokweqile, angakunikeza indlela emfushane yokusuka encazelweni evamile yophawu uye ekufundeni okunemininingwane yokuthi iplanethi iziveza kanjani.
