Bg 3.34

indriyasyendriyasyārthe
rāga-dveṣau vyavasthitau
tayor na vaśam āgacchet
tau hy asya paripanthinau

Word for word: 

indriyasya — of the senses; indriyasya arthe — in the sense objects; rāga — attachment; dveṣau — also detachment; vyavasthitau — put under regulations; tayoḥ — of them; na — never; vaśam — control; āgacchet — one should come; tau — those; hi — certainly; asya — his; paripanthinau — stumbling blocks.

Translation: 

There are principles to regulate attachment and aversion pertaining to the senses and their objects. One should not come under the control of such attachment and aversion, because they are stumbling blocks on the path of self-realization.

 

Krishna is saying what we should control Raga (attachment) and Dwesha which dwell in senses and sense objects so here Krishna is talking not about Prakriti and Vasana. In male and female body attraction about opposite sex is situated, one should regulate and should not go under their control. This cannot be unregulated. When some sadhu tells them not to indulge in sense gratification people will fell dwesa about him and don’t want to listen him and wanted to go away. If we leave devotees association because of Raga it will steal away our opportunity for spiritual advancement. 

Srila Prabhupada: Those who are in Kṛṣṇa consciousness are naturally reluctant to engage in material sense gratification.

As there can be accident even on royal road so even if someone follows Regulative principle, the relative principle itself will not protect us, regulative principle will just safe guard us, if we will indulge more in sense gratification then this desire will increase so much that it will break the barrier of regulative principle.

Our suffering is not because of our attachment our suffering is because of detachment from Krishna.

We should not be too much conscious or troubled  by our material attachment, sometime we may struggle or we may fall (even we fall we still should go ahead on our devotional service) and feel guilty, sometimes too much of guilt feeling can also become our temptation, temptation is anything which takes us away from Shri Krishna so lust and greed takes us away from Shri Krishna by promising that we will enjoy, guilt takes us away from Shri Krishna by creating a wall between us, by thinking we can never progress, guilt makes us self-centered and if we are self-centered we are not Krishna centered. We should feel guilt and it should act as impetuous for us to connect to Shri Krishna. If we are sick the feeling of sickness makes us feel of medicine not that any medicine will not work, that type of guilt is sudo-guilt, anything that discourages us from Krishna bhakti is not to be encouraged. If guilt is increasing our bhakti it is good as in the songs of Srila Bhakti Vinod Thakur but by guilt if someone thinks I cannot do Bhakti let us go through sense gratification that is useless. Always the governing principle is anukulyas he sankalpasa praticulas he varjanam. Our focus is now I serve Shri Krishna more and more not whether I will succeed or fail in temptation next time. 

Core devotional activity is hearing and chanting to develop taste for this we need to discipline our mind.

Which can be done by doing services, we do service as per our nature but we should also do service which are not as per our nature, we should not go and hunt for service which are not as per our nature but we should do as per need by his we make surrender.
