करणे घटस्य या बुद्धिर्घटोत्पत्ती न सा मता । एवं धर्मभ्युपायेषु नान्यधर्मेषु कारणम्,घटके निर्माणकालमें जिस बुद्धिका उपयोग है, वह घटकी उत्पत्ति हो जानेपर आवश्यक नहीं रहती, इसी प्रकार चित्त-शुद्धिके उपायभूत यज्ञादि धर्मोंका लक्ष्य पूरा हो जानेपर मोक्षसाधनरूप शम-दमादि अन्य धर्मोंके लिये वे आवश्यक नहीं रहते
karaṇe ghaṭasya yā buddhir ghaṭotpattau na sā matā | evaṁ dharmābhyupāyeṣu nānyadharmeṣu kāraṇam ||
Bhishma said: The practical know-how employed in making a pot is not regarded as still necessary once the pot has come into being. In the same way, ritual and other disciplines that serve as means toward dharma—such as sacrifices undertaken for purification—are not, after their purpose is fulfilled, the direct cause for other, higher disciplines; for the pursuit of liberation, one must rely on the distinct virtues like self-control and inner calm that are themselves the means to moksha.

Preparatory religious acts are useful as means (e.g., for purification), but once their intended result is achieved they are not the direct instrument for the next, higher goal; liberation requires its own specific disciplines such as inner calm and self-control.
In the Shanti Parva discourse, Bhishma instructs Yudhishthira on dharma and liberation, using the analogy of pot-making to distinguish between preliminary practices and the distinct virtues required for moksha.
