In civilized human society there must be the divisions of brahmana, ksatriya, vaisya and sudra, and everyone must properly execute his occupational duty in accordance with his division. Here it is described (svadharma-nisthah) that it does not matter whether one is a brahmana, ksatriya, vaisya or sudra. If one sticks to his position and properly executes his particular duty, he is considered a civilized human being. Otherwise he is no better than an animal. It is also mentioned herein that whoever executes his occupational duty (sva-dharma) for one hundred births (for instance, if a brahmana continues to act as a brahmana) becomes eligible for promotion to Brahmaloka, the planet where Lord Brahma lives. There is also a planet called Sivaloka, or Sadasivaloka, which is situated in a marginal position between the spiritual and material worlds. If, after being situated in Brahmaloka, one becomes more qualified, he is promoted to Sadasivaloka. Similarly, when one becomes even more qualified, he can attain the Vaikunthalokas. The Vaikunthalokas are targets for everyone, even the demigods, and they can be attained by a devotee who has no desire for material benefit. As indicated in Bhagavad-gita (8.16), one does not escape material miseries even if he is elevated to Brahmaloka (abrahma-bhuvanal lokah punar avartino rjuna). Similarly, one is not very safe even if he is promoted to Sivaloka, because the planet of Sivaloka is marginal. However, if one attains Vaikunthaloka, he attains the highest perfection of life and the end of the evolutionary process (mam upetya tu kaunteya punar janma na vidyate). In other words, it is confirmed herein that a person in human society who has developed consciousness must take to Krsna consciousness in order to be promoted to Vaikunthaloka or Krsnaloka immediately after leaving the body. Tyaktva deham punar janma naiti mam eti so rjuna (Bg. 4.9). A devotee who is fully in Krsna consciousness, who is not attracted by any other loka, or planet, including Brahmaloka and Sivaloka, is immediately transferred to Krsnaloka (mam eti). That is the highest perfection of life and the perfection of the evolutionary process.   (More...)
