think of following simile :
once upon a time, one bird egg hatch and this little chick thru whole it’s life is doctrine with fish doctrine ie. how to live as fish, when the moment come this little chick because of hv strong fully faith practice to swim & dive, then of course this it cost little chick lives.
for fish, flying is useless skill and waste of time to learn, for bird diving and live under water is as well useless and waste of time.
think of what will happen if there is a being in other universe that hv totally different set of nature law with our’s and practicing our dhamma ?
Just a little food of thought…
May I and all being in all universe free from suffering and attain arahat and nibbana….
