Free from attachment, free from egoism, full of a fixed (impersonal) resolution and a calm rectitude of zeal, unelated by success, undepressed by failure, that doer is called sattwic.
Gītā 18·26The sattwic doer is free from all this attachment, this egoism, this violent strength or passionate weakness; his is a mind and will unelated by success, undepressed by failure, full of a fixed impersonal resolution, a calm rectitude of zeal or a high and pure and selfless enthusiasm in the work that has to be done. At and beyond the culmination of sattwa this resolution, zeal, enthusiasm become the spontaneous working of the spiritual Tapas and at last a highest soul-force, the direct God-Power, the mighty and steadfast movement of a divine energy in the human instrument, the self-assured steps of the Seer-will, the gnostic intelligence and with it the wide delight of the free spirit in the works of the liberated nature.
