यदा यदा हि शिक्षणस्य गौरवर्भवति भारतः । अभ्यूथ्यानम्‌ अशिक्षास्य च मूर्खस्य निस्तारणम्‌ ।| परित्रानाय हि मूढाणां विनाशयच पण्डितम्‌ । अधमस्य संस्थापनार्थय सम्भवामि युगे युगे ॥

ज्ञ्यानं क्षीणं भवेत्‌ क्षणात्‌ बित्तकोषं विवर्धते । एतएव कोषात्‌ मन्वे ज्ञानादपि गरियषी ॥ गम्भीर ज्ञ्यान सम्पन्ना उत्कृष्ट गवेषणा सम्भवाः । अर्थहीनात्‌ ते पचन्ते निर्गन्धा इव किंशुकाः ॥

भज सम्पदं भज सम्पदं, सम्पदं भज मूढमते ||

शुक्ल ययुर्वेद: यथा शिखा मयूराणां नागानां मणय़ो यथा ॥ तद्‌ वेदांग शास्त्रणां गणितं मूर्धनि स्थितम्‌ ॥

वर्तमान श्वेतवराहकल्पे जम्बुद्वीपे: यथा पश्चात्‌-पुच्छ मयूराणां जोनाकीकीटाणां आलोकयः यथा ॥ तद्‌ पण्डित-अध्यापकाणां गणितज्ञ नराधमम्‌ ॥

गणितज्ञानाम् आवश्यकता केवलं पूर्णतायाः अधरसेवायाश्च कृते भवति, तेषां वास्तविकं मूल्यं नास्ति यतः ते धनं जनयितुं न शक्नुवन्ति ||

केवलं शिक्षायाः मूल्यं भवति यत् धनं जनयति|| अन्ये सर्वे विषयाः प्रहसनं निष्प्रयोजनं च ||

Teaching :

यदि कश्चन रुचिः नास्ति तर्हि एकः एव अनुसरणं कुरुत।

नकलीगणितज्ञानाम् निर्माणं मा कुरुत, ते भयानकाः सन्ति, कुत्रापि बकवासं प्ररोहयिष्यन्ति।

अरुचिकरेभ्यः व्याख्यानं न कुर्वन्तु।

इच्छुकस्य शिक्षकस्य शिक्षिकायाः ​​च कृष्णफलकस्य अपि आवश्यकता नास्ति।

भवन्तः केवलं इच्छुकान् एव पाठयितुं शक्नुवन्ति।

त्वं कस्मैचित् पाठयितुं न शक्नोषि।
