This is a test of advancement in devotional service. As stated in ÅšrÄ«mad-BhÄgavatam (11.2.42), bhaktiḥ pareÅ›Änubhavo viraktir anyatra ca: in bhakti, a devotee’s only attachment is Kṛṣṇa; he no longer wants to maintain his attachments to many other things. Although MÄyÄvÄdÄ« philosophers are supposed to be very much advanced on the path of liberation, we see that after some time they descend to politics and philanthropic activities. Many big sannyÄsÄ«s who were supposedly liberated and very advanced have come down again to materialistic activities, although they left this world as mithyÄ (false). When a devotee develops in devotional service, however, he no longer has attachments to such philanthropic activities. He is simply inspired to serve the Lord, and he engages his entire life in such service. This is the difference between Vaiṣṇava and MÄyÄvÄdÄ« philosophers. Devotional service, therefore, is practical, whereas MÄyÄvÄda philosophy is merely mental speculation.
