Hare Krsna Gurudeva
PAMHO, careful obeisances.
You were searching for 6 chakras in class online from Radhakund to Nitaigaurasundra.
Here are some references where SP mentions 6 Chakra.
SB 4.4.25 ( I think you were trying to quote this)
What does sincere mean in the context of "sincere inquiry"?
are all insincere inquiries absurd inquiries
HpS - I understand it to mean, enquiries that lead to some practical improvement in Krsna's service, rather than mental gratification like mixing different Fruti flovors to serve the whims of our tongue.
Thank for being a transparent consciousness.
