Ashtavakra Gita 11.3 -

The Sage brings another line of thinking to become free and delightful. Like many other dvandvas, adversity and prosperity in life are not uncommon. They are part of the world and its queer course. Whoever runs the world alone brings these. Leave everything to Providence and time. Time alone instrumented one’s birth. The same time will ensure one’s survival and end too. So many have lived and gone. ‘I shall also, likewise. The best will be to be poised and restful’. Thus think and feel assured.

Our senses alone reveal and interact with the world. In this course, the only factor to be regulated is the senses. Let the senses be calm and orderly.

Mind is the next factor to cause unsettlement, confusion and fear. Desire is the root cause of all agitation and unrest. So, do not take to desiring. Equally so, do not unduly grieve either. Once these two are moderated, it makes the mind equal to all dvandvas.

Sukha and duḥkha, happiness and unhappiness, are the only outcome sensory interactions bring about every time. Good and bad, friend and foe, gain or loss, life or death, all are external dvandvas, leading only to sukha and duḥkha in the mind. If one becomes equal to these, that will extend to all else. Such a one will be an embodiment of sāmya, evenness, which bestows full freedom, liberation, as Bhagavad Gita states (5.19 ).
