To state this in a subtle way: it is the divine feelings in the Manas waning day by day, until by the final hour, like the moon on the new-moon night, they are not seen in the sky of the heart, and there is smoke and darkness, that is, the time of being in a state of complete Ajñāna. This is what is called the dark fortnight. For one who leaves the body at such a time, it is the path of smoke. Such people reach the world of heaven and, as soon as that merit is exhausted, take rebirth.
