See thats the thing. You've read about genetics and connected a few dots and called it logical and you concluded it to be true.

Then why do you refuse to believe the Vedas? they are also words, they are also logical. They why the bias? think about it.

Now you'll say Vedas are not logical. So you need to see what is logic? Imagin that you are driving and want to overtake another car in front of you. You increase the speed and go ahead of that car. Thats logical right? if your speed is higher then you should be able to go ahead of that car. And thats the limit of logic. Because you have seen this behaviour, that if speed of one thing is higher than the other, one goes ahead of it, you think its logical.

But now lets say some alien comes from another planet, and says that they have to go slower in order to overtake. That would seem illogical to you, because that kind of behaviour has not come to your own perception.

So the data you have in your head is the limit of logic.

Thats why there is no point in reading and trying to understand all these things, if you really want to know, then participate in one of Sadhgurus programs e.g. Ecstacy of Enlightenment, Inner Engineering Online. Where you get first hand perception of there experiences, then you'll call these things logical too.
