He is a sage of steady mind
He is always in Krishna consciousness
He has exhausted all business of creative speculation

cHow one in Krishna consciousness is:
Equipoised (2.56) – because:
He accepts everything (happiness / distress) as Krishna’s mercy
Free from attachment, fear and anger (2.56) – because:
He is always daring and active, and fixed on the service of the Lord
He does not come under attachment / aversion
He never gets angry, whether successful or not
He is steady in determination
Unaffected by good and evil (2.57) – because:
The material world is anyway full of relativities and dualities, and there is always some upheaval
The soul is simply concerned with Krishna who is always all-good & Absolute
Such a Krishna conscious position is in perfect transcendental position called “Samadhi”
