denying the diVine principles (मेष -मा ईश, no lord), diVine instructions, adopting low behavior towards the higher beings, one falls from the T-over (north pole, meru) and descends upon prison earth in the body being punished (meru-dand, मेरुदंड)…to learn, to correct, to evolve & to ascend (ऊर्ध्वगति)…

as beings fall on earth…some get unconscious, some retain some conscious and are sub-conscious whereas some with lord’s grace regain their conscious…

those who learn the diVine principles and master themselves…they only ascend and never fall back on this temporary plane of sorrow and pain…

मामुपेत्य पुनर्जन्म दुःखालयमशाश्वतम,
नाप्नुवंति महात्मनः संसिद्धिं परमां गताः।
Bhagwad geeta, chapter 8, V15…

simpler things made complex and the terms are used without knowing their absolute meaning…
unconscious beings thru’ mass hypnotic phenomenon are made to believe that they are gods, they are awake, they are conscious but, in reality, they only become mass pretending beings…accepting any philosophy as spirituality but, yet unable to decode the very truth of this earthly reality…

hence, they descend (अधोगति) again and again… whereas one be-earth time is enough to work upon oneself and to be free forever…
