Subjective opinions of how best to engage in devotional services to Krishna are accepted by Him and His pure representatives if they align in pure love .Such love automatically and spontaneously aligns a devotees’ heart with the absolute, they will know in advance and be fully conscious of what is pleasing , such devotional efforts will be soaked with devotional sentiments and truth .There will be a complete absence of localised interests, thus they are all immediately harmonized with the absolute spiritual objective reality of a spiritual kingdom, and relished by Srimati Radharani, Sri Krishna and Their unlimited family and friends.
We could say in the words of Srila BR Sridhar Swami the subjective communes with the super subjective..

Much more on the developing devotional service soon .

The complete science with its various nomenclature is given by Srila Rupa Goswami.
