Material bondage is illusion because the living entity actually has no real relationship with the material world. Because of false ego, the conditioned soul identifies himself with matter. Therefore so-called liberation is simply the giving up of an illusion rather than release from actual bondage. Yet even if we think that the suffering of material illusion is real and that liberation is thus a meaningful release from suffering, the mere absence of material existence is still insignificant compared to the achievement of factual spiritual life, which is the positive eternal reality opposed to the negative illusion of material life. Ultimately, Kṛṣṇa consciousness, or pure love of Godhead, is the only significant, meaningful and permanent status for every living entity.
Since the darkness of night is caused by the absence of the sun, one would not experience night within the sun itself, nor would one experience individual days separated by nights. Similarly, within the pure living entity there is no material darkness and thus no experience of liberation from such darkness. When the conditioned soul comes to this platform of pure consciousness, he becomes fit to associate with the supreme pure, the Personality of Godhead Himself, in the Lord’s own abode.
