Even if you go to the highest planetary system, Brahmaloka, then there also punar āvartinaḥ, means the four principles of material existence, namely birth, death, old age and disease, they will accompany you. Wherever you go. You may have a long duration of life, but you have to meet death. That is compulsory. And as soon as you meet death, you have to enter into the womb of a certain type of mother and develop another body and come out again and begin another life. This is going on.
So Kṛṣṇa says in the Bhagavad-gītā, ā-bhrama-bhuvanāl lokāḥ punar āvartino 'rjuna: Even if you go to the highest planetary system, Brahmaloka, within this material world, that process will go on, repetition of birth, death, old age and disease. Because this material body, wherever you get it, either you are American or Englishman or Indian or moon planet or sun planet or Brahmā planet, Brahmaloka planet, anywhere you go, you'll get a certain type of body, but that material body is subjected to these four principles: birth, death, disease and old age.
