Nothing but lilas and nam, can fully stop the harmful urges. As I just heard once again in Antya 6 Chaitanya Bhagavata even Lord Brahma was struck by these urges in one pastime. And we know the very same thing happened to even lord shiva so what power do we have.
So many have fell down in previous Yugas just by a glimpse of witnessing some scene. Only Nityananda can help us.
Based on past experience however and other testimony.
When we succumb to harmful thoughts, maya makes us feel ashamed to even do bhajan.
But we simply need to remember that Nityananda never disqualifies any soul for Harinam bhajan, however dire the circumstances.
I have as well felt in the beginning. So maya makes us feel ashamed to do bhajan in our hopeless condition. but if we only remember the all forgiving and compassionate nature of nityananda and force it then very quickly the taste shifts from from harmful thoughts to bhakti.
While otherwise it may be harder without the mercy of nityananda.
We simply have to remember Nityananda’s compassionate nature and not allow maya to drown us in shame hiding our heads in the sand from the full OCEAN of mercy of Harinam which Nityananda is giving us.
