Astanga Hrudaya
मासेन याति शुक्रत्वमन्नं पाकक्रमादिभिः।सन्त्तता भोज्यधातूनां परिवृत्तिस्तु चक्रवत्॥६६॥
some say, after six days; and yet others after one month, after undergoing series of paka (digestion and transformation). The transformation of bhojya dhatus (nutrient tissues, small qualities of essence of the preceeding tissue) goes on uninterrupted like the (movement of) wheel
