At the time of Krishnavatara, there were two sisters Radha and Radhika, Radhika was a Sagunopasaka and Radha, Nirgunopasaka. Radha constantly chanted the name of Krishna, while Radhika was engrossed in the physical form of Krishna. She was extremely sad because Krishna had gone away to Mathura. She gave up food and drink and said, ‘Krishna, in my heart I have been keeping Your lotus form fresh with my tears. Now even my tears have gone dry. How can I now preserve Your form in my heart? My heart, which is Your gift, I am now returning to You. What else is there that I can offer at Your feet? Accept my salutations and myself.’ She surrendered herself to Krishna. Radha saw this. She had thought that Nirgunopasana was superior to Sagunopasana, but after seeing the total surrender of Radhika, she realised the greatness of Sagunopasana. After this, she constantly meditated on the name and form of Krishna. (DD on 14.10.1999, pp 259)
Because of Lakshmana’s intense devotion to Rama, he has also followed Him like a shadow. He brought fruits, flowers and tubers from forest to serve Rama and Sita, and himself fasted. Every moment of his life, he spent in the service of Rama. He put his both his body and mind in the service and worship of Rama as a Sagunopasaka. (SSS Vol.32 Part II, p. 43)
