“But are javana citta also required for daily life like pushing open a heavy door..”
Yes. That is likely.
The difference is that if there is no lobha, dosa, moha involved in that effort, it will not have created “kammic seeds” to bring vipaka in the FUTURE.
– Whatever javana power created would be used for getting the job done at that time.
But we need to keep in mind that mundane alobha, adosa, adosa also can have kammic consequences, i.e., create kammic energies that can bring vipaka in the future. See, “Six Root Causes – Loka Samudaya (Arising of Suffering) and Loka Nirodhaya (Nibbāna)”
– So, in a strict sense, only Arahant’s actions will be TOTALLY free of kammic consequences.
