We will know about truth when we don't make any difference among those that love us, and those that reject us, because we will not act like an answer but as an initiative of the Spirit that finds rejoicing in the art of loving and it is that the true reason goes beyond the superficial, it extends to the regions where mystery inhabits, and love always takes the light of compassion, even to the dense darkness.

For this reason,  good is eternal and for this reason truth doesn't change neither varies. It is constant, persevering, as the love of the beloved to his/her loved one. The spiritual science is the conscious practice of divine life.
