Extract from a Tablet of ‘Abdu’l‑Bahá
Know thou that before maturity man liveth from day to day and comprehendeth only such matters as are superficial and outwardly obvious. However, when he cometh of age he understandeth the realities of things and the inner truths. Indeed, in his comprehension, his feelings, his deductions and his discoveries, every day of his life after maturity is equal to a year before it.
