I quit Pariprashnena several months ago
But the site doesn't have account deletion button so it may look I'm still there.
Whoever was/is asking me anything there, please do it here, in forum, by pm or email.
Re 10 days after death when the soul still stays on earth:
This is hinted at in Garuda Purana (trans. J.L. Shastri/A board of scholars, Motilal Banarsidass, Delhi 1982):
2.10.82 Whatever pinda the sons or kins give him during the ten days, the same unites the Vayuja body with the pindaja body.
2.15.74 On the eleventh day and the twelfth, the soul of dead eats to his fill.
2.15.76 On the thirteenth day, the soul of the dead is taken to the High Way. Now he assumes a body of the pinda and feels hungry by day and night.
2.18.39 Here [in Yamaloka] he [dead man] gives up his dreadful body, of the measure of arm, which he derived within ten days from the ten pindas gifted to him by his descendants.
