Indra (Rig Veda 1.8) - Madhuchanda Vaisvamitra:

इन्द्र त्वोतास आ वयं वज्रं घना ददीमहि ।
जयेम सं युधि स्पृधः ॥१.८.३॥
Indra Tvotaasa Aa Vayam Vajram Ghanaa Dadiimahi |
Jayema Sam Yudhi Sprdhah ||1.8.3||

• इन्द्र त्वा ऊतास (Indra Tvaa Uutaasa): O Indra, Protected by you.
• वयं वज्रं घना ददीमहि (Vayam Vajram Ghanaa Dadiimahi): We bear the hard Vajra.
• जयेम सं युधि स्पृधः (Jayema Sam Yudhi Sprdhah): We become victorious against the opponents.

Comments:

- In this mantra, the performer of the Yagna is mentioned to bear the Vajra himself.

- A unique feature of the Vedas is self-transformation of human beings and not just work output. This self-transformation is embedded in the Yagna Cycle. In the first half of the Yagna Cycle, Indra was awakened by the performer of the Yagna (through repeated invocations). In the second half of the Yagna Cycle, Indra awakens the performer of the Yagna with his power. With this self-transformation, the performer of the Yagna tries to transform the world.

- Indra, who was awakened with Vajra in hand, gives the Vajra of inner strength to the performer of the Yagna. Bearing that Vajra he becomes victorious against the opponents.

- As mentioned earlier, the opponents with whom Indra fights are very powerful. They are the Vrtras or coverings, who covers the Cosmic Order with a shell of individualism. With the shell of Vrtra an individual will create his own individual world and forget that he is part of the Cosmic Order. Cut off from the Cosmic Order, life becomes unsustainable in the long run.

- Thus Yagna comprises of initiative, awakening by divine grace and ownership of upholding Rita after divine grace. It is not simply looking up for help while himself sitting idle. Starting from lighting the Agni, there is a cycle of flow of divine power in the form of drinking the Soma. The final work gets done by this awakened power.

यः कुक्षि सोमपातमः समुद्र इव पिन्वते ।
उर्वीरापो न काकुदः ॥१.८.७॥
Yah Kukssi Soma-Paatamah Samudra Iva Pinvate |
Urviir-Aapo Na Kaakudah ||1.8.7||

• यः कुक्षि सोमपातमः (Yah Kukssi Somapaatamah): Whose Abdomen after drinking Soma.
• समुद्र इव पिन्वते (Samudra Iva Pinvate): Spreads like an Ocean.
• उर्वीः आपो न काकुदः (Urviih Aapo Na Kaakudah): Like much water falling from mountain (i.e. like waterfall).

Comments:

- In this mantra, Indra is said to be spreading after drinking the Soma.

- As mentioned earlier, even though the Yagna is performed by individual self-effort, the grace which dawns is for collective good. Here, awakened by an Yagna, Indra is spreading his power far and wide, for collective good.
