What they are
An astra is not simply a powerful weapon. It is an instrument belonging to a named deity — Brahmā, Indra, Agni, Vāyu, Varuṇa — which is invoked by a spell, discharged, and recalled by another spell, and which behaves according to whose it is. Viśvāmitra confers a long list of them on the boy Rāma in the first book, together with the formulae for recall, and the transfer takes place in a single night on the road.
They are governed by a hierarchy and by counter-weapons. A weapon of Brahmā is answered by a weapon of Brahmā; serpent-weapons are undone by Garuḍa, the enemy of serpents; armour given by Brahmā is proof against everything except Brahmā's own shaft. The war books assume a reader who follows this system.
In the war
The fighting at Laṅkā is largely a contest of astras. Indrajit binds both brothers with serpent-weapons and later cuts down the host with the Brahmā weapon; Lakṣmaṇa kills Atikāya with the Brahmā weapon only after Vāyu tells him nothing else will pierce the armour; and Rāma finally kills Rāvaṇa with the arrow of Brahmā that Agastya gave him in the forest — after his charioteer has to remind him he is carrying it.
Reading them
The astra system is one of the ways the epic distinguishes ranks of combatant. Ordinary fighters use ordinary weapons; the vānaras fight with trees and rocks and are formidable without any spells at all; and a small number of figures on both sides operate at the level where the gods' own instruments are in play. Rāma's possession of that armoury from the age of about sixteen is what makes the rest of the poem's outcomes plausible.
Later tradition and the purāṇas expand the catalogue considerably, and popular retelling has treated the astras as a taxonomy to be enumerated. Vālmīki names many and describes few.
A system, not a stockpile
The astras behave according to rules the epic expects its audience to know. They belong to particular gods and share those gods' natures; they are invoked and recalled by formula, so possession is knowledge rather than ownership; they can be countered by weapons of the same or higher rank; and using one carelessly has consequences the user cannot undo.
The Bāla Kāṇḍa's list is a catalogue of names rather than a description of effects. What matters in the narrative is the hierarchy, which decides every important fight.
Restraint
The epic is also interested in when they are not used. Rāma carries the Brahmā weapon from the third book to the sixth and does not draw it, and at the end has to be told by his charioteer that the time has come. He refuses to use a weapon of that class against Kabandha or against ordinary rākṣasas.
The one occasion he threatens to use one improperly — against the ocean — the poem treats as a loss of temper, and the ocean gives way rather than see it happen.
