Guru Nanak Dev Ji maharaj gave us naam simran which utilizes mantra, dhyan and pranayam. It is extremely powerful with all that combined. First my grandpa taught me everything is within the body. You should learn to properly breathe from your diaphragm if you don't know how. Stay conscious of yourself properly breathing from the diaphragm throughout the day. To see if you breathe properly take a deep breath. If you breathe properly your shoulders should not have gone up only the belly should expand and contract. <---- this is just proper breathing to always keep you relaxed. Now on to the meditation part. Realize your journey is from naabhi to trikuti. First month I sat down with my dhyan on the naabhi to train my dhyan. The middle of my chest where the heart is and God resides is another place I really enjoyed putting my dhyan like when I would fall asleep. Once your dhyan is trained then nothing can distract your mind. Many people complain that they cannot focus but that is due to their dhyan not being properly trained. Most people don't know how to properly enter the Naabhi. To enter the Naabhi put your dhyan at the bottom of your belly button and keep it there. If you put your finger straight in your belly button it would be the area the bottom of your finger touches. Do this for 15 minutes per day for a month. Soon your dhyan will become so powerful you immediately go into a extremely relaxed state perfect for naam japna the moment you put your dhyan at the naabhi. Pranayama will happen naturally with mantra you just need to re-wire your mind backwards. Naturally navel goes out when you say Vahe and in with Guru but you need to change to Vahe gentle natural pull navel in a bit and Guru it goes out. You will notice then you won't get tired either. Everytime you sit down for naam japna. First you stabilize your sit bones into a comfortable position. Then you start with putting Dhyan at the bottom of the belly button for 5 minutes while staying silent then you start the naam japna out loud Vahe-Guru, Vahe-Guru. After about 5 minutes of jaap bring your dhyan from bottom of the belly button to your mouth while continuing jaap. You will know your dhyan is at the right place because if you open your eyes you will be looking directly at your nose when your dhyan is on your mukh. "Dhun me dhiaan, Dhiaan mai jaaneya gurmukh akath kahanee." just keep your dhyan on the dhun of Vahe-Guru then. Get the book "Sikhism & Spirituality" by Rabinder Singh Bhamra. Depending on how much effort you put in that'll dictate how long it takes for the Kundalini shakti to awaken in the Naabhi and for person to reach Naam. Takes couple months usually. The method I have told you about will take you all the way. You don't need any other jugti. It's a process of awakening there are no secrets if you put in the work you get the result just like anything else in life. It's good to find some sangat to do it with.
