The same life that throws us into life to suffer or enjoy, as may be deserved, decrees that the friends and the relatives who are like unto each other must incarnate together.
Until by reason of differentiation of character they cannot under any law of attraction remain in company.
Not unless and until they become different do they separate from each other.
And who would wish to be eternally tied to the side of uncongenial relatives or acquaintances merely because there was an accident of birth!
For our aid, also, this law works well and ceaselessly.
"Those whom you help will help you in other lives".
