To enter the kingdom of God, we must change bodies.
However, he who targets only the higher material planets, edenic, paradisiacal, can keep the garment or etheric body, but he will have to leave his fleshly envelope of dense matter, made of earth, water, air, fire and ether.
On the other hand, the one who developed the yoga of powers can, at the critical hour of death, by bringing the vital force between the two eyebrows, choose his destiny.
Thus, he who no longer wants to maintain the slightest connection with the material world can, in less than a second, gain the transcendental kingdom, the spiritual world, where he will live in his spiritual body, a body adapted to the spiritual atmosphere. It is enough for him to desire to leave the world and to abandon his two bodies; that of dense matter and the ethereal body, and then to move the vital force to the top of the skull where is the orifice by which he will leave his body.
Such an undertaking is easy for one who has developed the practice of yoga. Of course, man has his free will and therefore, if he does not wish to be delivered from the material universe, he will be able to occupy the position of Brahma and visit the planets where the materially perfect beings live, who have all powers to control gravity, space and time. There is no point in abandoning his ethereal body. He must only get rid of his dense material body.
Each planet has a particular atmosphere, and if you want to go to a given planet, you must adapt your body to the climatic conditions that are unique to it. One who only targets the upper planets of the galaxy, can keep the ethereal body, but will have to leave his dense material envelope.
Similarly, we must completely change our bodies if we want to go to the transcendental planets of the spiritual world. We must absolutely abandon our two bodies, the ethereal body and the body of dense matter, in order to clothe the spiritual body, which alone will allow us to enter the spiritual world. This is the true resurrection.
