Lower Nature

Deprive not yourselves of the unfading and resplendent Light that shineth within the Lamp of Divine glory. Let the flame of the love of God burn brightly within your radiant hearts. Feed it with the oil of Divine guidance, and protect it within the shelter of your constancy. Guard it within the globe of trust and detachment from all else but God, so that the evil whisperings of the ungodly may not extinguish its light.

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 325

Every good thing is of God, and every evil thing is from yourselves. Will ye not comprehend?

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 149

Fear God, and follow not your desires which have altered the face of creation.

Bahá’u’lláh, The Proclamation of Bahá’u’lláh, p. 74

Follow not the promptings of the self, for it summoneth insistently to wickedness and lust.

Bahá’u’lláh, The Kitab-i-Aqdas, p. 41

As long as man is a captive of habit, pursuing the dictates of self and desire, he is vanquished and defeated. This passionate personal ego takes the reins from his hands, crowds out the qualities of the divine ego and changes him into an animal, a creature unable to judge good from evil, or to distinguish light from darkness. He becomes blind to divine attributes, for this acquired individuality, the result of an evil routine of thought becomes the dominant note of his life. May all of you be freed from these dangers and delivered from the world of desires that you may enter into the realm of light and become divine, radiant, merciful, Godlike.

‘Abdu’l-Bahá, Divine Philosophy, p. 133-134

Briefly; the journey of the soul is necessary. The pathway of life is the road which leads to divine knowledge and attainment. Without training and guidance the soul could never progress beyond the conditions of its lower nature which is ignorant and defective.
