They are described by Prahlada Maharaja in the 7th Canto of the Srimad Bhagavatam as follows:To hear about Sri Visnu's transcendental name, His form, His characteristics, His possessions and His pastimes and to hear and chant about His pastimes, to remember them, to serve the lotus feet of the Lord, to respectfully offer service to the Lord, to offer prayers to the Lord, to become His servant, to consider the Lord one's best friend and to offer Him everything-these nine processes are recognized as pure devotional service.Our initiatives need your support: https://rzp.io/l/brajsundardasSupport our cause Paypal: https://paypal.me/bdpayments?country.x=IN&locale.x=en_GB
