Murari Sevaka Asrama accepts all devotees as worthy of worship, because all devotees following the precepts of the four sampradayas are very dear to Krishna.
Srimad Bhagavatam states (9.4.57):
sadhubhir grasta-hrdayo bhaktair bhakta-jana-priyah
Basically, we should live by Sri Caitanya’s 3rd Siksastaka prayer:
trinad api sunichena
taror api sahishnuna
kirtaniyah sada harih
One should chant the holy name of the Lord in a humble state of mind, thinking oneself lower than the straw in the street; one should be more tolerant than a tree, devoid of all sense of false prestige and should be ready to offer all respect to others. In such a state of mind one can chant the holy name of the Lord constantly.

Srila Narottama dasa Thakura
O Lord, you are an ocean of compassion and the friend of the destitute. Please mercifully give me your glance. I have fallen into the ocean of illusory mundane life where I am surrounded by whale-eating timingila fish in the form of lust. They are trying to swallow me, therefore O My Lord, please protect me.
Since my birth, I have offended you again and again and failed to worship you sincerely, without duplicity. Nevertheless, You are my only shelter. O Lord of my life, please do not neglect me, there is no one more fallen than I.
O Syama! You are famous as the savior of the fallen. If you forsake me, I have nobody else. Even if I am an offender, You remain as my only hope, in the same way as the husband for a chaste wife is her only hope.
O Lord of my life, please listen to my prayer. You are the Supreme Lord. Please do not forsake me. Even if I commit offenses, still You are my Master. Please give me some service and engage me as your servant.
Lust is piercing my heart. I do not know my own good. I cannot vanquish the bad desires in my mind. O Master, please keep me close to You. You are a wish-fulfilling desire-tree. Please show your compassion to everyone by accepting me.
O Lord, throughout the three worlds, You will not find anybody as fallen as I. Deliver me and become known as “Narottama-pavana” (the deliverer of Narottama). O Syama, let your name, Patita-pavana, deliverer of the fallen, be known throughout the universe. O Giridhara, lifter of Govardhana Hill, please accept me as your servant.
O my Lord, Narottama dasa is very unhappy. Please make me happy by engaging me in your bhajana and sankirtana. O Lord, my greatest fear is that I will not be able to overcome the obstacles in the path of bhakti. Therefore, I pray to You constantly.
