Both Poorva Slokaas and Uthara Slokaas of each Ashtapasi must be sung. Naamavali may be taken up, time permitting, after each Ashtapasi (after Uthara sloka) or atleast at the end of each Sargam.
After the 24th Ashtapadi, Paartha Saarathi Geetham "Bhajatha Prema Krupaanidhi Maadhavam" in Thodi to be sung after the slokam: "Nakkhaniyamida Khandoon". This is followed by:
Kalyaana Tharangam: "Aaalokaye Rukmini Kalyaana Gopaalam"
Daasarvaal Kruthis
Pooja Paddhathi Kramam
Upachaara Keerthanam.
If Poorna Ashtapadi is done before Kalyaanam, then you can stop at any end of Sargam, as per time permitting and continue the balance during Paddhathi Bhajan, Dolothsavam and 22nd, 23rd and 24th on Kalyaanam day. In such case, the Parthasaarathi Geetham and Kalyaana Tharangam should be sung after the Maangalya Dhaaranam, but before Anjaneya. After Poorna Ashtapathi, it is customary to recite the first starting sloka at the end, to indicate that this is a continuous process and does not end with this programme.
There is a practice of offering different palahaarams (total 24) at the end of each Ashtapadi. This is possible only for some people. However, two Kela Fruits and Betal Leaves & nut Nivedhyam is a must after each Ashtapadi.
