1. It is useless to take diksha and not following rules & regulations properly. Then there is no meaning of diksha and Guru also has to suffer.
2. If a disciple doesn’t follow sincerely, then Guru has to suffer physically & mentally also. So if a disciple has some love for his Guru, he will follow rules & regulations strictly.
Guru is like an axe who cuts the attachments deep within one’s heart. Real diksha means that he has no attachment to anything of this material world.
Guru means Sad-guru, otherwise he cannot take you back to godhead.
If you want to know the heart of Guru, then you should follow his instructions strictly. Then seeing your sincerity, he will reveal secrets before you.
If you follow exactly what Guru says, Guru will protect you from maya.
Remain a fool before Guru. Do what he says. Then see the result.
