BG Chap 14 - Symptoms by which one knows himself to be beyond guṇas
One who is beyond the guṇas does not hate or lament, the appearance of illumination (the effect of sattva), activity (the effect of rajas) or delusion (effect of tamas) thinking that they would cause suffering by transforming into their respective effects, nor desires their disappearance along with their products thinking that they would cause happiness. Such a person is beyond hatred and attachment, and this cannot be known to others, but to oneself. This is the internal quality of the person beyond the modes. He does not lament when the effects of the guṇas appear, nor rejoices when the effects disappear.
