Man (5): Can you give any explanation about the spiritual, around the earth? If they are all luminous?
Madhudviṣa: He wants to know something about psychic phenomena.
Prabhupāda: Psychic phenomena is the subtle materialism. There are two material conditions: one gross condition, one subtle condition. Gross condition is created by the five elements—earth, water, fire, air and ether. And the subtle elements are mind, intelligence and ego, false ego. So all these eight elements, they are material. One section is gross, and another section is subtle. So the psychology means the subtle material elements. It is material; it is not spiritual. It is subtle.
Man (6): At rebirth do we all return as a male if the previous existence was a male, or do we change? (laughter)
Madhudviṣa: He is asking when you take birth again do you take birth as the same sex, or do you change your sex?
Prabhupāda: No, no. Just like you change your body, you change your shirts, it is not necessary that you will get the same type of shirt. No. That you . . . just like if your present shirt you want to change, and you go to the store and you purchase another shirt and coat, that will depend on your choice and the price you can pay. It is not necessarily that you will get the same type of shirt and coat. Therefore, when we change our body, there is no guarantee that we get the same type of body. A male can get a female body. There are many instances like that. And a female can get the male body. A man can get animal body, like that. So in the Bhagavad-gītā it is said, dehāntara-prāptiḥ (BG 2.13), echange of body. But what kind of body you are going to change, that will depend on your own work.
