I was in Bangkok, Thailand when, Ronit, my husband's cousin, told me her  
personal story.  Before there was a mikvah in Bangkok, women would have to 
travel down to the seaside and tovel themselves in the sea.   Over  20 years 
ago, the Lubavitcher Rebbe had instructed the four Jewish families living in 
Thailand to construct a Mikveh.  They took a long, long time obeying his wishes, 
because they  reasoned, "who would want to go to the Mikveh in this foreign 
country?" Presently, thank G-d, the little Mikveh that is in the Chabad House in 
Bangkok is used  by immigrants, Jewish visitors, and many Israeli 
families.
Anyway, going back to her story, Ronit would have to prepare 
herself at home, travel down with her husband to the nearest seaside town called 
Pattaya about 2 hours away, and with her husband driving the "Water-scooter", go 
out into the sea and tovel herself, then make the return two hour journey. 
This went on for a couple of years, until one day something very amazing 
happened.  
Ronit's time to go to the Mikveh came. As usual she prepared 
herself at home, and with her husband, drove down to the seaside town. They 
rented a water scooter, and went into the sea, a good way out to ensure 
privacy.   Ronit immersed herself into the sea, and then got on the scooter. Her 
husband turned the key on the scooter, but the engine did not "take".  He tried 
again and yet again, many times, until they both realized  -  the motor was 
dead, totally!   They decided to try to swim for shore with great apprehension, 
for as anyone who has ever swam in the Andaman Sea knows, the current is 
extremely strong, and sweeps you out to sea without you even realizing it. "It 
still did not register with us", she told me, matter-of-factly, "That we were 
going to die! Suddenly, we saw that the current was driving us inexorably 
towards a big, craggy rock formation in the sea. We realized that it was 
basically all over for us.   All I could think about was how my Mother's face 
was going to look when they told her that her daughter was smashed to pieces on 
the rocks!" 
 Faced with certain death, they both lifted up their faces, 
raised their voices, and in unison, instinctively  screamed out to Hashem  "SAVE 
US HASHEM!!!   DONT LET PEOPLE SAY THAT WE GOT KILLED DOING YOUR 
MITZVA!! 
Suddenly, a strong wave came out of the blue and just brought them safely back to shore!! Hashem listened to their cries and saved them! "That was the month that I conceived", Ronit told me quietly and emotionally. "After two agonizing years of trying to have a baby, THAT month, Hashem finally let me conceive. The son I gave birth to, we called Doron "a gift". According to the pain is the gain.
Thank G-d, today, we do not have 
to go into dangerous waters, with fear of the unknown, or travel 2 hours each 
month to do Hashem's will.   We  can go to a warm, clean, safe Mikveh, with 
inviting waters just ready for us with all the modern conveniences, and even 
luxurious surroundings. But even if we had to go to a muddy hole in the ground, 
we would do so in order to do Hashem's will, because He is our maker and He 
knows what we need and what benefits us and our relationship with our spouse, 
our children and  Himself.
