There is no rekah beyond which a child can go
and that is not lakshman rekha
yes it is the mind control
that a mother plays on her child
Neither in this world
nor in other world
a child can never cross this rekha
A mother so important never
 knows how she creates it
how she uses is and when
it is implied.For her emotions
are always to protect her child,
her brain never works for her child.
It is attachment that can pull
the child towards her or
can deviate away from her.
