attain to the moon at death. These elevated souls live on the moon for about 10,000 years (by demigod calculations) and enjoy life by drinking  soma-rasa . They eventually return to earth. This means that on the moon there are higher classes of living beings, though they may not be perceived by the gross senses.

 एकया यात्यनावृत्तिमन्यया वर्तते पुनः ॥२६॥

TRANSLATION
According to the Vedas, there are two ways of passing from this world—one in light and one in darkness. When one passes in light, he does not come back; but when one passes in darkness, he returns.
The same description of departure and return is quoted by Ācārya Baladeva Vidyābhūṣaṇa from the  Chandogya Upaniṣad . In such a way, those who are fruitive laborers and philosophical speculators from time immemorial are constantly going and coming. Actually they do not attain ultimate salvation, for they do not surrender to Kṛṣṇa.
