वितर्कविचारानन्दास्मितारूपानुगमात्सम्प्रज्ञातः।
vitarkavicārānandāsmitārūpānugamātsamprajñātaḥ।
[वितर्क विचार आनन्द अस्मिता रूप अनुगमात् संम्प्रज्ञातः।
vitarka = deliberation of logic; vicāra = deliberation of a topic; ānanda = happy; asmitā = awareness of 'I am'; rūpa = form; anugamāt = accompanied by; saṁmprajñātaḥ = equilibrium state with knowledge;]
Equilibrium states with form accompanied by knowledge are progressively: deliberation on logic (vitarka), deliberation on topic (vichāra), and happy awareness of 'I am' (ānanda asmita).
Among the equilibrium state with knowledge and form (samprajnāta samādi) deliberation on a topic is better than deliberation on logic, staying in the awareness of 'I am' with happiness is better than deliberation on topic.
