SB 7.13.9

na yater asramah prayo
 dharma-hetur mahatmanah
santasya sama-cittasya
 bibhryad uta va tyajet
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
A peaceful, equipoised person who is factually advanced in spiritual consciousness does not need to accept the symbols of a sannyasi, such as the tridanda and kamandalu. According to necessity, he may sometimes accept those symbols and sometimes reject them.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
There are four stages of the renounced order of life — kuticaka, bahudaka, parivrajakacarya and paramahamsa. Herein, Srimad-Bhagavatam considers the paramahamsas among the sannyasis. The Mayavadi impersonalist sannyasis cannot attain the paramahamsa stage. This is because of their impersonal conception of the Absolute Truth. Brahmeti paramatmeti bhagavan iti sabdyate. The Absolute Truth is perceived in three stages, of which bhagavan, or realization of the Supreme Personality of Godhead, is meant for the paramahamsas. Indeed, Srimad-Bhagavatam itself is meant for the paramahamsas (paramo nirmatsaranam satam). Unless one is in the paramahamsa stage, he is not eligible to understand the Srimad-Bhagavatam. For paramahamsas, or sannyasis in the Vaisnava order, preaching is the first duty. To preach, such sannyasis may accept the symbols of sannyasa, such as the danda and kamandalu, or sometimes they may not. Generally the Vaisnava sannyasis, being paramahamsas, are automatically called babajis, and they do not carry a kamandalu or danda. Such a sannyasi is free to accept or reject the marks of sannyasa. His only thought is “Where is there an opportunity to spread Krsna consciousness?” Sometimes the Krsna consciousness movement sends its representative sannyasis to foreign countries where the danda and kamandalu are not very much appreciated. We send our preachers in ordinary dress to introduce our books and philosophy. Our only concern is to attract people to Krsna consciousness. We may do this in the dress of sannyasis or in the regular dress of gentlemen. Our only concern is to spread interest in Krsna consciousness.
