Purport: 

When a living entity desires to serve the Lord in transcendental loving service, the Lord helps the devotee in so many ways as the caitya-guru, or the spiritual master within, and thus the devotee can perform many wonderful activities beyond material estimation. By the mercy of the Lord even a layman can compose prayers of the highest spiritual perfection. Such spiritual perfection is not limited by material qualifications but is developed by dint of one’s sincere endeavor to render transcendental service. Voluntary endeavor is the only qualification for spiritual perfection. Material acquisitions of wealth or education are not considered.
