俱舍論疏 9.75

9.75

論「謂母胎中至形相滿位」，此明胎中位漸增也。羯剌藍者，此云和合，或云雜染，或云凝滑。頞部曇者，此云皰，如皰起故。閉尸，此云軟肉。鍵南，此云堅肉。鉢羅奢佉，此云支節。後髮、毛、爪等，乃至色根形相滿位，總是第五位也。若依正量部說，髮等已去名第六位。

The Śāstra says: "Namely, from within the mother's womb … to the stage where the physical form and faculties are complete." This clarifies the gradual development through the stages within the womb. Kalala is translated here as 'mixture', or as 'defilement', or as 'coagulated slime'. Arbuda is translated here as 'vesicle', because it arises like a bubble. Peśī is translated here as 'soft flesh'. Ghana is translated here as 'hard flesh'. Praśākhā is translated here as 'branches and joints'. After that, hair on the head, body hair, nails, and so forth, up to the stage where the physical form of the material sense faculties is complete, all constitute the fifth stage. If relying on the Sammatīya school, from the appearance of hair onwards it is called the sixth stage.
