In plain words
There is a spiritual meaning to this, and a scientific meaning.
The moment they are born from the mother's womb, they cry “kevvu, kevvu”, without a smile; why they cry I shall tell you now: see the way it shows itself day after day.
That is, as time goes on we learn that our life is full of troubles, losses, sorrows and griefs. So the child cries at the very start as a sign of the sorrows and griefs to come: this is one spiritual meaning. While in the mother's womb, the child's ten senses are filled with water. The child is filled with water. All around the child, inside and everywhere, there is water. There is an inner meaning in the child's crying the moment it is born. This is a secret of God's creation. Because the nose, the eyes, the ears and the mouth, all these organs, are filled with water, crying clears it all, and breathing in and out begins. A child that does not cry like this the nurses hold by the legs, turn head down and slap with cold water. Then the child cries. When it cries, the blood flows properly and breathing in and out begins. The body stays well and healthy. When breathing in and out does not begin and the blood does not flow, the body turns blue. The moment it comes out, danger arises to the child's health and to its very life. That is why crying the moment it is born is natural to every child. But this Tulasīdās did not cry when he was born. Because he did not cry, the women gathered there: alas, what is this, this child should cry the moment it is born. This is not a proper birth. There must be some flaws. Thinking he was some ghost's child, an ill-omened child, a demon's child, they began to talk in many ways. As if to bear this out, that very night Tulasī was seized by a high fever. The women thought it came from weariness and gave her this medicine and that, but she did not get well. On the second day she was in greater danger. On the fourth day, the day of Ekādaśī, the mother died.
When Tulasī died, there was no one to look after the child. So they gave the child to a woman in the house next door. They asked her to bring him up.
