Prabhupada is relevant enough for you to write a post about him, at the very least.
Accepting a guru is like saying that I am not qualified to approach God directly. It is basically an expression of personal humility, and also a glorification of God's majesty.
You can't even approach the President of the US directly -- you must go through his cabinet and his security. Clearly, God is more powerful and majestic than any president.
Do you really think that you're qualified to approach God directly???
