Agnir Vrittraani Janghanad (Verse 4)
Agni (fire) destroys the demons (vritras).
Agni implies ‘knowledge’ and Vritta 'darkness of ignorance'. Just as Agni destroys the darkness, in the same manner we should use 'the fire of knowledge' for the destruction of Kama (lust), Krodh (anger), Moha (attachments) and Ahamkaar (arrogance) – the five inherent enemies of man. The fire of knowledge is capable of destroying these enemies. Ignorance (darkness) can be destroyed by knowledge of self.
Agne! Nah Drishe Devah Hi Asi (Verse 10)
Agni is the deity, who shows us the (right) path.
Agni is known for his capability to annihilate darkness. As soon as there is light, darkness vanishes and as a result the surroundings become clearly visible. It shows us the right path when it is dark. So, quite rightly Agni has been referred to as the destroyer of darkness and the torch bearer of human beings.
Nah Rayim Vansate (III Verse 2)
Agni blesses us with wealth.
Fire was perhaps one of the first natural sources of energy which became evident to primitive man. Quite naturally, he was mesmerized by its power which was both constructive as well as destructive. Man has been exploiting this energy to his advantage since time immemorial. Had it not been for this natural source of energy, all the progress mankind has witnessed would never have been possible. Not a single factory could run without it. Hence, man's awe of Agni is quite understandable and this was the reason it has been rightly eulogized as the giver of wealth.
