在诸内分期(antardaśā)、特殊大运与次级大运中,若大运之主落于友好星座或本座,或得擢升(exaltation),并居于吉祥分宫与强势位置,则此运成为赐予增长与兴盛者。

It frames worldly rise and decline as time-bound (daśā-based) outcomes, encouraging discernment and steadiness—so one uses favorable periods for dharma and inner progress rather than mere enjoyment.
By showing that external prosperity depends on changing periods, it indirectly supports bhakti as the stable refuge: one should anchor the mind in devotion while navigating favorable and unfavorable daśās.
Jyotiṣa Vedāṅga: interpretation of major and sub-periods (daśā/antardaśā) and how dignity (own sign, exaltation, friendly placement) and strength factors indicate growth-oriented results.
