When a person’s father is alive, that person need not perform kuzhi tharpanam; only those without fathers alive must perform kuzhi tharpanam.
During the 10 days of asaucam:
Must not render services at Perumal temples
Perumal must not be brough in procession to homes as part of Dolotsavam
Must not light Purattasi mavilakku and celebrate Acaryan Tirunakshatrams
If the person observing asaucam is chief member of the household, asaucam is applicable for that entire household. Hence, if a Perumal Tirunakshatram must be celebrated without fail, it must be celebrated by one who is not tainted by the asaucam and at a different place that is not tainted. If there are sons, these can be performed through them. Elders say that it is better to avoid these during the 10 days of asaucam.
Varusha Pirappu, Navarathri, Deepavali, Karthikai, Kanu, etc., if they occur during the 10-day period, they must not be celebrated.
