In this world two types of people are free from all anxiety and merged in great happiness: one who is a retarded and childish fool and one who has approached the Supreme Lord, who is beyond the three modes of material nature.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
द्वावेव चिन्तया मुक्तौ परमानन्द आप्लुतौ । यो विमुग्धो जडो बालो यो गुणेभ्यः परं गतः
dvāveva cintayā muktau paramānanda āplutau | yo vimugdho jaḍo bālo yo guṇebhyaḥ paraṃ gataḥ
