Service in spiritual path is the culmination of Bhakti [Devotion]
towards God by discharging our Dharma [duty] towards our fellow beings
resulting in Sat-Karma [good actions]. Bhakti without Dharma and
Sat-karma is like that force of current [Bhakti] in the river [Self]
which without a path [Sat-karma] to flow is of no use and cannot be
merged [Dharma] with ocean but evaporates and finally dries away.
