Regarding the proposed trip to Kenya, the next step I have already advised to Tamala in this connection. I understand he is coming to London very soon, and you can discuss with him. But one thing is that Mr. Parikh was talking of this Sankirtana Party to Africa since a very long time. There is no direct correspondence with us. It is difficult to say how it will be a fact in future.
Regarding requirements and recommendations in the Vedic system of selecting partners for marriage, there is a Vedic system, but that cannot be done here. It should be made under the guidance of the guardians and the selection should be made on the basis of astrological equilibrium. So it is not possible to introduce such system in the present age. The only selection is that both the boy and the girl should be Krsna conscious, and the boy may be older than the girl at least by 2 to 5 years.
Your first question about the jiva's form with particular reference to Bhagavad-gita 8/18 purport "during the nighttime they have no form." "During the nightime they have no form" means there is no material form. The simple understanding is as we are transmigrating from one material form to another, so actually in this material world we have no fixed form. Similarly when we are spiritually perfect we develop the spiritual form to live eternally in the spiritual world. In the spiritual world there are exactly the same things as we see here; namely the land, water, trees, birds, beasts, human beings, etc., and all of them are spiritual as all the varieties here are material.
So these things can be understood when one is advanced in self-realization. The real form of the living entity is eternal servant of Krsna. Now this spiritual form is developed when he enters into the spiritual world.
