本ダシャティは、インドラの勝利の力を中心に据え、戦いと競争において障碍を打ち砕き、祭儀を妨げるものを除き、誹謗・敵対の言葉を退けてソーマ祭の吉祥な成就を確保するよう祈る。続いてウシャス（曙光）を招き、馬を繋いで到来させ、儀礼の明るい「開き」を告げて繁栄をもたらす。さらに、羊毛の濾し器で清められたソーマ（パヴァマーナ）が「周り、周り」と流れつつ諸神を遍満し、陶酔の力で供物を力づけ、すべての神々を包摂して祭主に福徳と成就（サウバガ）を与えることを説く。

Frequently Asked Questions
It links ritual success to divine power: Indra breaks impediments and defeats hostility, while the rite is auspiciously opened by Uṣas and energized by purified Soma.
Uṣas signals the rite’s timely beginning and brings “saubhaga” (prosperities), and Soma—once filtered and exhilarating—becomes the shared power that reaches the gods and supports Indra’s victory-giving role.
Sāyaṇa takes vṛtra as “āvaraṇa” (obstruction), so vṛtratūrasi means Indra has the power to break through impediments—especially those that hinder the sacrifice and its intended results.
