Vaishnava Samhita. Shri Vyasadasa Charitam II. Vol II Book VI Chp 3 Shlokas 6 - 7

न दीक्षां नोपदेशञ्च न मन्त्रं तन्त्रमेव च 
अपेक्षते कृपासिन्धुर्भक्तभावकुतूहलः  ||

रसिकैः प्रेमिकैर्भक्तैरर्चितः प्रेमपूर्वकम् 
तत्तद्भावानुसारेण नानालीलां करोति सः ||

The compassionate Shri Krishna is so merciful that He merely conducts Himself in accordance with the temperaments (Manobhava) of the bhaktas. He does not relish deeksha or upadesha or mantras or ritualistic practices. Shri Krishna who is worshiped with loving devotion by the prema bhaktas who are great rasikas, displays divine pastimes suited to their moods.
