Without a siksa-guru you cannot progress an inch. Here, Visakha is the siksa-guru of Krsna – by her help, He realized Sri Radha's bhavas. Without a siksa-guru, you cannot realize these topics. Sometimes I see that there is more importance of a siksa-guru because, out of etiquette, diksa-guru cannot generally open his heart to his disciple. Siksa-guru is like a bosom friend...

Guru is like Krsna. Krsna inspired the heart of Brahma and said, "I am the embodiment of all tattva-jnana, tattva-vijnana, and all love and affection. Only this form of mine was present before the creation, only that form exists now, and later, after the destruction of everything material, only I will exist.
