Premanand Maharaj Ji
Do I need to do something separate from my daily work to practise bhakti?
Make your work your bhajan
Treat your duty as worship, chant the name inside while doing it, and do it by dharma for others' happiness. Then it becomes bhajan.
Take your duty itself as worship of Bhagwan and do it while chanting the name inside. There is no need to do anything separate day and night; do what you do in line with dharma.
