santoṣo vai svarga-tamaḥ santoṣaḥ paraṁ sukham
santoṣo vai svarga-tamaḥ santoṣaḥ paraṁ sukham |
tuṣṭer na kiñcit parataḥ sā samyak pratitiṣṭhati ||
(Mahābhārata: 12.21.2)
“Satisfaction is verily the highest Svarga. Satisfaction is the highest happiness. When that is fully established [in the mind], there is nothing more fulfilling.”
