Paramparā of the Atharva Veda and Purāṇas; Definition of a Purāṇa
Daśa-lakṣaṇam
रक्षाच्युतावतारेहा विश्वस्यानु युगे युगे । तिर्यङ्मर्त्यर्षिदेवेषु हन्यन्ते यैस्त्रयीद्विष: ॥ १४ ॥
rakṣācyutāvatārehā viśvasyānu yuge yuge tiryaṅ-martyarṣi-deveṣu hanyante yais trayī-dviṣaḥ
在每一个时代,不失真之主阿周陀都会在此世间于禽兽、人类、圣仙与诸天之中示现降生。凭其诸般神圣戏游,祂护持宇宙,并诛灭违逆吠陀之敌。
The protective activities of the Lord, indicated by the word rakṣā, constitute one of the ten fundamental topics of a Mahā-purāṇa, or a great Purāṇic literature.
This verse says the infallible Lord descends again and again to protect the universe and to eliminate those who oppose the Vedic path and dharma.
Those who hate or undermine the Vedic order—Vedic knowledge, sacrifice, and dharma—are called trayī-dviṣaḥ, regardless of whether they appear as humans, sages, demigods, or other beings.
Align your life with dharma and śāstra—study sacred texts, avoid philosophies that erode devotion and integrity, and take shelter of the Lord through bhakti, trusting that divine protection supports sincere practice.
