The Puranic description is as follows:
One can construct a house like a pregnancy room and decorate it with flowers, cloth and jewels. Murtis or pictures of the gopis, gopas, Nanda, Yasoda, Vasudeva, the Devatas, as well as the asuras (in sleeping state) should decorate the place.
One can draw a sarvatobhadra mandala, place a kumbha on it and place a metal plate over that filled with sesame. On that one should place the murti of Devaki with Krsna. One should carry out puja according to the vidhis, starting with the purvanga karmas (purificatory activities such as bhuta sudhi), manasa puja and ending with offering of external articles. One should use many flowers, much gandha and many varieties of fruits.
One should worship Devaki with the mantra "namo devyai sriyai".
After worshipping Krsna one should worship Vasudeva and others with "om vasudevaya namah" etc.
When the moon rises one should offer arghya to the moon saying:
ksirodarnava sambhuta atrinetra samudbhava
grhanarghya sasankesa rohinya sahito mama
jyotsnapate namastubhyam namaste jyotisam pate
namaste rohini kanta arghyam me pratigrhyatam
Then offer arghya to Krsna:
jatam kamsa vadharthaya bhu bharottaranaya
ca
devatanam hitarthaya dhara samsthapanaya ca
kauravanam vinasaya daityanam nidhanaya ca
grhanarghyam maya dattam devaki sahito mama
sri krsnaya devaki sahitaya saparibaraya
laksmi sahitaya arghyam namah
One may then perform full puja of Krsna according to the rules using the mantras:
etat padyam (footwater) om yajnesvaraya yajna sambhavaya yajna pataye govindaya namo namah
idam snaniyam (bath) om yogesvaraya yoga sambhavaya yoga pataye govindaya namo namah
idam vastram (cloth) om yajnesvaraya yajna sambhavaya yajna pataye govindaya
namo namah
idam alankaram (ornaments) om yajnesvaraya yajna sambhavaya yajna pataye
govindaya namo namah
esa dhupah (incense) om yajnesvaraya yajna sambhavaya yajna pataye govindaya namo namah
esa dipa (lamps) om yajnesvaraya yajna sambhavaya yajna pataye govindaya namo namah
idam naivedyam (food) om visvesvaraya visva sambhavaya visva pataye govindaya namo namah
idam tambulam (betal nut and spices) om dharmesvaraya dharma sambhavaya dharma pataye govindaya namo namah
The next day one should feed the brahmanas and give gifts.
