four maras
The four external and internal hindrances or obstacles to our spiritual progress. They are: 1) the mara of the (contaminated) aggregates (Skt: skhandha-mara); 2) the mara of delusions (Skt: klesha-mara); 3) the mara of the Lord of Death (Skt: mrityu-mara); and 4) the mara of the deva's son (Skt: devaputra-mara), the demon of desire and temptation.
