Atma, Ananda is not thamasic joy or rajasic joy or sattri joy. Rajasic joy can give a lot of happiness and you have to put in effort for it to get those joys but in the end, it's always disappointing. Thamasic joy is destructive. It slowly is a negative effect on character. Satua rajasthamas are constituents of the mind. So enjoying the name of God, the satric joys.
