What business an Apsara will have with a settled married life which is dedicated to rearing up children?
What is the basic purpose of their existence?
They are endowed with unmatched physical beauty and sexual attraction which help them while alluring males of all sorts for whatever purpose it may be.
Then, isn't having children, being married to one person, leading a chaste married life a hindrance for them?
Moreover, how many males they sexually cohabit with? Must be numerous.. and a woman who cohabits with more than 5 males is technically a prostitute.
1-44. Dharmarâjan said :-- O Chaste One! Without serving the Gods, the
Karma ties can never be severed. The pure acts are the seeds of
purities and the impure acts lead to impure seeds. If any Brâhmana
goes to any unchaste woman and eats her food, he will have to go
ultimately to the Kâlasûtra hell. There he lives for one hundred years
when ultimately he gets a human birth when he passes his times as a
diseased man and ultimately he gets purified. Those women who are
addicted to their (one) husbands only are called Pativratâs. Those
addicted to two persons are named Kulatâs; to three, are called
Dharsinîs; to four, called Pums’chalîs; to five, six persons, called
Ves’yâs; to seven, eight, nine persons are called Pungîs; and to
more than these, are called Mahâves’yâs. The Mahâves’yâs are unfit
to be touched by all the classes.
Devi Bhagavatam 9.35
Hence, they are like "celestial prostitutes" in that sense.
- And the two Risis were very much surprised on seeing them. 25-27. They saw near to them the Cupid with his attendants Menakâ, Rambhâ,
Tilottamâ, Puspagandhâ, Sukes'î, Mahâs'vetâ, Manoramâ, Pramodvarâ,
Ghritâchî, Châruhâsinî, the expert in music, Chandra Prabhâ, the
cuckoo voiced Somâ, the lotus eyed Vidyunmâlâ, Kânchana malinî, and
others.
- Eight thousand and five hundred Apsarâs and long multitudes of the hosts of Cupid, the Munis saw and were surprised.
- Then those prostitutes of the Devas, dressed with their heavenly ornaments and the heavenly flowers, appeared before the Munis
and bowed down their heads on the ground.
- The Apsarâs began their enchanting songs, exciting much passion and rarely heard or seen in this world.
Devi Bhagavatam 4.6
They are manifestation of Rajas Guna as per Manu Smriti which is basically associated with passion (and activity).
Manu Smriti 12.47. The Gandharvas, the Guhyakas, and the servants of
the gods, likewise the Apsarasas, (belong all to) the highest (rank
of) conditions produced by Activity.
But according to Devi Bhagavatam they are linked with Tamas only as their behavior shows (unhindered sexual activities with countless males).
The best, middling, and worst are all sprung from Prakriti.
Those women that are sprung from Sattva Guna are all very good natured
and chaste; those that are sprung from Rajo Guna are middling and very
much attached to worldly enjoyments and do their selfish ends and
those that are sprung from Tamo Guna are recognised as worst and
belonging to the unknown families. They are very scurrilous, cheats,
ruining their families, fond of their own free ways, quarrelsome and
no seconds are found equal to them.
Such women become prostitutes in this world and Apsarâs in the Heavens. The Hermaphrodites are parts of Prakriti but they are of
the nature of Tamo Gunas.
Devi Bhagavatam 9.1
So, in short, for an Apsara, to be faithful to any one particular male and to be a dedicated and an affectionate mother is a serious hindrance. To be not affectionate towards their children, forsaking them is the sort of behavior we can expect of the Apasaras.
