The Vedas teach that the soul is divine, only held in the bondage of matter; perfection will be reached when this bond will burst, and the word they use for it is, therefore, Mukti - freedom, freedom from the bonds of imperfection, freedom from death and misery.
It is too often believed that a person in his progress towards perfection passes from error to truth; that when he passes on from one thought to another, he must necessarily reject the first. But no error can lead to truth. The soul passing through its different stages goes from truth to truth, and each stage is true; it goes from lower truth to higher truth.
Nothing endures, nothing is precise and certain (except the mind of a pedant), perfection is the mere repudiation of that ineluctable marginal inexactitude which is the mysterious inmost quality of Being
All perfection is there already in the soul. But this perfection has been covered up by nature; layer after layer of nature is covering this purity of the soul.
Our Soul is a spark of the Divine. It is pure and perfect. Evil deeds merely obstruct our vision of the true nature of our Soul. Through good deeds we can become conscious of this perfection again.
