You have struck on one of the keys of the Great Neterian Truths, namely that the first three are a setup for the last one. In order to have success in the last one it is necessary to have understanding of the teaching and be properly founded in the Neterian wisdom. Then that wisdom acts as support and impetus for the “striving” that lies ahead. The first carries the highest wisdom. The second establishes the necessary re-balancing order that is to be engendered. The third imparts the understanding that if one devotes oneself to the realization of the first two then there will be freedom from the delusion of not realizing and experiencing the wisdom first hand. The forth imparts the means by which the wisdom given in the first three is to be realized.
The issue of striving is innate in the human experience.
“To Know God, strive to grow in stature beyond all measure; conceive that there is nothing beyond thy capability. Know thyself deathless and able to know all things, all arts, sciences, the way of every life. Become higher than the highest height and lower than the lowest depth. Amass in thyself all senses of animals, fire, water, dryness and moistness. Think of thyself in all places at the same time, earth, sea, sky, not yet born, in the womb, young, old, dead, and in the after death state.”
-ANCIENT EGYPTIAN PROVERB
Therefore, what is needed is the perspective of relinquishment of stress through the understanding that having listened to the wisdom and having made the decision to follow its path, that the goal exhorted by the teaching will be arrived at in due time if the goal being striven for is righteous and the shedy practice is qualitative.
