I know absolutely nothing about the text or the author you cited.
But the 70 year part, and the copper, and the gold all sound like symbolism to me.
I provide a longer quote so that the context of the argument given by Bahaullah becomes evident:
Quote,"These same people, though wrapt in all these veils of limitation, and despite the restraint of such observances, as soon as they drank the immortal draft of faith, from the cup of certitude, at the hand of the Manifestation of the All-Glorious, were so transformed that they would renounce for His sake their kindred, their substance, their lives, their beliefs, yea, all else save God! So overpowering was their yearning for God, so uplifting their transports of ecstatic delight, that the world and all that is therein faded before their eyes into nothingness. Have not this people exemplified the mysteries of “rebirth” and “return”? Hath it not been witnessed that these same people, ere they were endued with the new and wondrous grace of God, sought through innumerable devices to ensure the protection of their lives against destruction? Would not a thorn fill them with terror, and the sight of a fox put them to flight? But once having been honored with God’s supreme distinction, and having been vouchsafed His bountiful grace, they would, if they were able, have freely offered up ten thousand lives in His path! Nay, their blessed souls, contemptuous of the cage of their bodies, would yearn for deliverance. A single warrior of that host would face and fight a multitude! And yet, how could they, but for the transformation wrought in their lives, be capable of manifesting such deeds which are contrary to the ways of men and incompatible with their worldly desires?
It is evident that nothing short of this mystic transformation could cause such spirit and behavior, so utterly unlike their previous habits and manners, to be made manifest in the world of being. For their agitation was turned into peace, their doubt into certitude , their timidity into courage. Such is the potency of the Divine Elixir, which, swift as the twinkling of an eye, transmuteth the souls of men!
For instance, consider the substance of copper. Were it to be protected in its own mine from becoming solidified, it would, within the space of seventy years, attain to the state of gold. There are some, however, who maintain that copper itself is gold, which by becoming solidified is in a diseased condition, and hath not therefore reached its own state.
Be that as it may, the real elixir will, in one instant, cause the substance of copper to attain the state of gold, and will traverse the seventy-year stages in a single moment. Could this gold be called copper? Could it be claimed that it hath not attained the state of gold, whilst the touchstone is at hand to assay it and distinguish it from copper?
Likewise, these souls, through the potency of the Divine Elixir, traverse, in the twinkling of an eye, the world of dust and advance into the realm of holiness; and with one step cover the earth of limitations and reach the domain of the Placeless. It behooveth thee to exert thine utmost to attain unto this Elixir which, in one fleeting breath, causeth the west of ignorance to reach the east of knowledge, illuminates the darkness of night with the resplendence of the morn, guideth the wanderer in the wilderness of doubt to the wellspring of the Divine Presence and Fount of certitude, and conferreth upon mortal souls the honor of acceptance into the Ridván of immortality. Now, could this gold be thought to be copper, these people could likewise be thought to be the same as before they were endowed with faith.
O brother, behold how the inner mysteries of “rebirth,” of “return,” and of “resurrection” have each, through these all-sufficing, these unanswerable, and conclusive utterances, been unveiled and unraveled before thine eyes. God grant that through His gracious and invisible assistance, thou mayest divest thy body and soul of the old garment, and array thyself with the new and imperishable attire.
Therefore, those who in every subsequent Dispensation preceded the rest of mankind in embracing the Faith of God, who quaffed the clear waters of knowledge at the hand of the divine Beauty, and attained the loftiest summits of faith and certitude , these can be regarded, in name, in reality, in deeds, in words, and in rank, as the “return” of those who in a former Dispensation had achieved similar distinctions. For whatsoever the people of a former Dispensation have manifested, the same hath been shown by the people of this latter generation. Consider the rose: whether it blossometh in the East or in the West, it is nonetheless a rose. For what mattereth in this respect is not the outward shape and form of the rose, but rather the smell and fragrance which it doth impart." Unquote.
Can it be symbolic and the argument is valid, please?
