其次又当究分合分合者言乎其出没也夫脉之为脉非徒然而生顿然而有其出也必有自然之来则有分水以导之其没也必有所止则有合水以界之郭氏云地有吉气随土而起支有止气随水而比又曰支之所起气随而始支之所发气随而钟此古人论气脉之源流也气随土而起故脉行必有脊气随水而比故送脉必有水气起于支之始故上有分脉钟于支之终故下有合有合无分则其来不真为其内无生气之可接也有分无合则其止不明为外无堂气之可受也有分有合则有来有止有出有没则龙穴融结的定无疑然后为全气之地也然有大分合小分合真地融结则有三分三合穴前后一分合起主龙虎所交二分合祖龙至山水大会三分合也小合则为小明堂大合则为大明堂合于龙虎内则为内明堂合于龙虎外则为外明堂各不相乱如此是又不可不知也
浮沉论 其次又当别浮沉浮沉者言乎其表里也夫脉有隂阳故有浮沉隂脉常见乎表所谓浮也阳脉常收乎里所谓沉也大抵地理家察脉与医家察脉无异善医者察脉之隂阳而用药善地理者察脉之浮沉而立穴其理一也夫三隂从天生以其隂根于阳也故隂脉必上小而下大其出口也必尖三阳从地出以其阳根于隂也故阳脉必上大而下小其出口也必圆后之观脉者不必问其何如但口尖者皆隂□其脉浮于表口圆者皆阳□其脉沉于里此一定不易之法若又推而广之则凸者脉浮凹者脉沉微细者脉浮粗重者脉沉众髙一低者脉浮众低一髙者脉沉以此相乗除则隂阳之理得矣
浅深篇 其次又当定浅深浅深者言乎其凖的也夫浅深得乗风水自成故卜地者必以浅深为凖的宜浅而深则气从上过宜深而浅则气从下过虽得吉地而效不应者为此故也大概先观来脉之隂阳次防四山之从佐且如脉入首强作穴凹出口圆此皆脉浮而穴阳宜浅来脉入首弱作穴凸出口尖此皆脉沉而穴隂宜深故曰浅深得乗风水自成深浅之法多端至理莫过于是也切要辨认入首隂阳虾须界合明白若当深而浅当浅而深差于咫尺之间反吉为凶矣经曰地吉葬凶与弃尸同正此义也世俗装卦例论九星白法以定寸尺者大谬也
