This chapter examines the nexus of Vedism and astrology (Jyotiḥśāstra) in the work of the famous polymath Varāhamihira (fl. 550). In its use of ritual conventions, Varāhamihira’s texts demonstrate the influence of Atharvan ritual in astrological circles. It also clarifies importance of the yātrā, or war march, in figurations of kingship. The chapter shows how the ritual narrative of the war-bound king came to be incorporated in the royal ritual of consecration (abhiṣeka) and how, through this ritual appropriation, new, non-Vedic ritual actors would come to participate in Vedic ritual forms. In particular, Varāhamihira applies the technique of bali (food exchange) to undermine the aspersive, abhiṣeka based format of Atharvan śānti, which relied exclusively on śānti water and Atharvan mantras. The ritual-astrological nexus offers a counterpoint to early Dharmaśāstric conceptions of warfare, which tend to mute details of astrological timing for military action, and hence supress possible debates over fatalism.

Reciprocity can explain cooperative behaviour among non-kin, where individuals help others depending on their experience in previous interactions. Norway rats ( Rattus norvegicus ) cooperate reciprocally according to direct and generalized reciprocity. In a sequence of four consecutive experiments, we show that odour cues from a cooperating conspecific are sufficient to induce the altruistic help of rats in a food-exchange task. When rats were enabled to help a non-cooperative partner while receiving olfactory information from a rat helping a conspecific in a different room, they helped their non-cooperative partner as if it was a cooperative one. We further show that the cues inducing altruistic behaviour are released during the act of cooperation and do not depend on the identity of the cue provider. Remarkably, olfactory cues seem to be more important for cooperation decisions than experiencing a cooperative act per se . This suggests that rats may signal their cooperation propensity to social partners, which increases their chances to receive help in return.
