The devotee should patiently follow the rules and regulations of devotional service so that the day will come when he will achieve, all of a sudden, all the perfection of devotional service – Narada Bhakti Sutra, Code 05, Purport.
The Lord can be served simply by adoring Him and accepting Him.
Srimad Bhagavatam 2.9.36,
The currency notes, although paper, are issued by the government, they have full value. Similarly, this material world though temporary, but because it is an emanation from the Lord, it has its full value. The Vaishnava philosopher knows how to utilize it properly, whereas the Mayavadi philosopher fails to do so.
