In plain words
Many fearful deeds are done in the world; we must search out the reason they happen. Because selfless service has dwindled, senseless desires have grown great. Prema and service, the two, are wings to us, like a bird that soars on its wings; following the ways of that bird, we must reach the goal with speed.
Embodiments of the divine Ātma!
What rouses man and carries him to a higher level is desireless service. What gives man's mind and intellect all the strength and ability they need, and awakens his humanness, is desireless service alone. For man's rise, mere activity is not enough. Prema, kindness, morality, honesty, sympathy and forbearance are utterly necessary. Without these noble qualities it is not possible for man to practise niṣkāma karma. The joys and sorrows man undergoes every day, the attachments and hatreds he works up, the vāsanās for sense objects he tastes: for all of these the root cause is the agitations of the mind. The dual feeling of "this is mine, that is yours" is the root cause of these agitations. The selfish feeling, "Let the world go any way it likes; I alone must be safe," is the root cause of this duality. The fruit of selfish feelings is the root cause of attachment and hatred. The man who thinks that the body alone is "I", and that my family, my wealth and my own standing alone matter to me, is merely a selfish life. For such a man Satya itself is Asatya. Asatya itself keeps turning into Satya.
To remove the dirt in the heart of such a hardened man, service is the chief path. It is essential to recognise the truth that human birth has come only for niṣkāma sevā, not for selfishness. These acts of service must not be done merely for name and fame. Service must not be done to make one's own authority known in the world. Service must not be done to fulfil one's own selfishness and self-interest through service to the world. Such services do not earn the name of service; they may be regarded as a process carried out for selfishness and self-interest.
