#on duty

वेदमनूच्याचार्योन्तेवामिनमनुशास्ति ॥
सत्यं वद । धर्मं चर ॥
स्वाध्यायान्मा प्रमदः ।
आचार्याय प्रियं धनमाहृत्य प्रजातन्तुं मा व्यवच्छेत्सीः ।
सत्यान्न प्रमदितव्यम् । धर्मान्न प्रमदितव्यम् ।
कुशलान्न प्रमदितव्यम् । भूत्यै न प्रमदितव्यम् ।
स्वाध्यायप्रवचनाभ्यां न प्रमदितव्यम् । देवपितृकार्याभ्यां न प्रमदितव्यम् ॥
मातृदेवो भव । पितृदेवो भव । आचार्यदेवो भव । अतिथिदेवो भव ॥

Having taught the Vedas, the Ācārya thus enjoins the āśramaresidents:

Speak truth; walk in dharma (do your duty; do righteous acts) |
Be not heedless of self-study |
Having given agreeable wealth to the ācārya, do not sever the line of descendants |
Never fall from truth; never fall from dharma (duty, righteousness) |
Never overlook your own welfare (self-care), never neglect your prosperity;
Never neglect self-study and propagation (of the Vedas, of knowledge) |
Never neglect works (your duty) for the Gods and for the Fathers (ancestors) |
Treat your mother, father, teachers and guests like deities |

Taittirīya Upaniṣad, Śikṣā-valli, Ekādaśa Anuvākaḥ
