Arthashastra
"यान् यज्ञ संघैस् तपसा च विप्राः स्वर्ग एषिणः पात्र चयैश् च यान्ति । क्षणेन तान् अप्य् अतियान्ति शूराः प्राणान् सुयुद्धेषु परित्यजन्तः ॥
Beyond those places which Bráhmans, desirous of getting into heaven, attain together with their sacrificial instruments by performing a number of sacrifices, or by practising penance are the places which brave men, losing life in good battles, are destined to attain immediately.
english translation
