There are two types of devotion – one type is pushed by the need to follow rules, the other is pushed by the need to love Krsna. The first is called vaidhi-bhakti, the second raganuga-bhakti.
The utility of vaidhi bhakti is very limited unless it is a smaller component within raganuga-bhakti. Vaidhi bhakti does not allow one to develop love for Krsna in Vrindavan, it instead allows one to develop love for a Narayana expansion of Krsna in Vaikuntha.
To push someone to follow a rule, simply out of the idea that following rules is a good thing, is therefore a relatively useless endeavor.
Ragabhakti (the passion to love Krsna) can be aquired by hearing about the extreme attractiveness of Krsna, it does not come by following or not following rules. It has nothing at all to do with rules. Hearing Krsna’s enchanting pastimes, hearing about his extraordinary qualities, observing his wonderful beauty, and participating in the singing of his lovely name – these are the things that give rise to the type of divine devotion that is not pushed by a need to observe rules and regulations, but is instead motivated passionately by a urge to love Krsna more and more directly.
All efforts should be directed towards this goal, there is no need to ask people to follow rules, especially arbitrary ones. We should instead ask people to hear and chant about Krsna. That is the best medicine for all ills. All the rules are regulations automatically and spontaneously follow a person who has sincere affection for Sri Krsna.
