Devotion is not a physical Sentiment
Devotion is a type of love which comes from the soul and includes currents of respect and veneration. In such a state of love, one tries to provide comfort and convenience for the object of his devotion. He is prepared to suffer all types of inconveniences, and is happy only when the object of his devotion is pleased and in comfort. For his Beloved he sacrifices his body, his mind, his wealth, his beauty, his intellect and even his life. All these are surrendered at the feet of the Lord as the material of worship. In other words, he eliminates his ego completely.
On the other hand, physical sentiment or love always aims at the lover’s own happiness. In other words, he makes the object of his love an instrument for his own comfort and enjoyment.
