rajasi pralayam gatva
karma-sangisu jayate
tatha pralinas tamasi
mudha-yonisu jayate

"When one dies in the mode of passion, he takes birth among those engaged in fruitive activities; and when one dies in the mode of ignorance, he takes birth in the animal kingdom."

Why only one sloka for both rajas and tamas qualities, while one full sloka for satva quality? These two qualities -rajas and tamas- are to be discarded, then why waste one more sloka! We have to regard rajo and tamo qualities as our enemies and satva quality as our freind. Rajasi = [when ] rajo [quality, was prominent], pralayam gatva = [if the person] reached death. Here pralayam does not mean the occasional deluge but the daily happening death among living beings. Karma-sanghi = [those] involved in Karmas, like performing various yagnas to attain swarga, etc. Jayate = is born [among such people]. He is reborn amidst persons interested and performing Karmas for reaching Heaven and enjoying life for greater length of time than on this Earth. This is because at the time of death, that person had rajo quality dominating. We have seen rajo quality has the symptoms of lust and desire. Tamasi = [person with] tamo quality, pralina = dying, mudha-yonishu = in senseless species, jayate = [he is] reborn. When tamo quality is predominant at the time of death, a person is reborn in inferior species like animals, where there is no scope for development of intellect. That is he is reborn with the darkness of ignorance. When we act senselessly, we are chided as 'mudha' [மூடன்]! Thus the three qualities dominant at the time of death, result in rebirths in various circumstances - satva amidst intellects, rajo amidst haughty group and tamo amidst inferior animals, with no scope for development of intelligence. We will now take leave of this Kshetram.
