1. "Dekha thi Sikhi - The type of Sikhi you take on because you see someone else do it. "Dekh" = To see. This one does not last very long. Guruji does not accept this ("parvaan") type of Sikhi.

2. "To Get Something From Guruji" Sikhi - Gianiji called this "Hirs thi Sikhi". This is where one tries to please the Guru to get something done from Him. All other methods have failed, why not go to Gurdwara and do some Seva, maybe I get what I want. Guruji does not accept this ("parvaan") type of Sikhi either.

3. "Kauf thi Sikhi" - "Kauf" fear. The fearful Sikhi. Somebody told you that you must take amrit, otherwise something will happen. Very rampant in India a while ago. People where so scared, that they would ask where an Amrit Sanchaar was being held.



4. "Sidak thi Sikhi" - This is the type of Sikhi undertaken by a Sikh that is without any pressure, fear, or greed. It is simple done to set one's life in accord in this world and the next. Guruji accepts this Sikhi. Gianiji mentions all the martyrs in the Sikh faith who never gave up on it no matter what punishment they had to endure.

5. "Prem thi Sikhi" - "Prem" = Love. This was given to Bhai Nand Lal Ji. This type of Sikhi, Guruji accepts as well.
