If we can train up nice wife, or the society trains the girls to become nice wife, she becomes a great source of energy to the husband. dharma-artha-kāma-mokṣāya dharā sampra . . . and if they are polluted, they become source of the saṅkara, varṇa-saṅkara.
The exact example of varṇa-saṅkara is the hippies at the present moment, all over the world, not only in the Western countries but in India also. So the population, hippie population, means saṅkara population. So increase of such population means narakāyaiva, naraka, hellish, hellish condition of life in this life, also in the next life. At that time, to live . . . actually we have practically seen in recent year, especially in Calcutta, it has become a hellish life. The population, the younger generation, is so polluted, so contaminated, that you cannot safely walk in the street. Anywhere, the young boys they can encircle you and rob you. You cannot say. The police cannot help, the government cannot help. So these unwanted children, without being trained up in the varṇāśrama system, they become the cause of hellish life in this life, also after death.
After death, according to Vedic regulation, piṇḍa-udaka, piṇḍa, offering Viṣṇu prasādam and water at least once in a year, it is required by the family members. In . . . according to Vedic culture, there is one month fixed up in a year when all people will offer piṇḍa and udaka to the forefathers. Tarpana. Tarpana. Week or fortnight, for one fortnight. So the idea is that if the forefather in that family has not achieved a proper life . . . sometimes, due to sinful activities, too much attachment, a man becomes ghost. Ghost . . .
There is ghosts: bhūta preta piśāca. Not only this life, demonic life, but after death also there are ghostly life. They do not get this gross body. They remain in the subtle body—mind, intelligence and ego. Due to their gross sinful life, they are punished by not getting a gross life. Because without getting a gross life, we cannot enjoy. With mind, I cannot enjoy rasagullā. I must have the tongue, I must have the hand, fingers, I can pick up, then . . . in the mind, I may think of eating or collecting rasagullā, but actually I do not get the taste.
So gross body is required, because every living entity in this material world, they have come to enjoy. Kṛṣṇa bhuliyā jīva bhoga vāñchā kare pāśāte māyā tāre jāpaṭiyā dhare (Prema-vivarta 6.2). This is the beginning of our material life. When we forget to render service to Kṛṣṇa, immediately we get a material body offered by the material nature.
