Here you go.
1. Well many scholars have made it simpler to see the step by step enshrined in Sri Guru Granth Sahib Ji. You have to remember the 3 golden principles
Naam Japna
Meditation. The Sikh tradition has been to repeat God's/Guru's name out loud, whilst focusing on the sound. Hold His image in your mind, let yourself be completely immersed in remembrance of God/Guru. All senses focused towards Him.
Vand Chhakna
Consume what you have shared. Simple enough. Share your possessions with others, knowledge, materials, food, goals, desires, spirituality, etc.
Sachi Kirat Karni
Righteous action. Is also honest action. To speak the truth and hold on to it as your only support. To know what is right and wrong in a given situation, and act upon it without losing focus.
These are the basics, and they cannot be stressed enough.
2. If you want to go further, you might also want to start noticing in yourself (in addition to practicing the above): greed (accumulation of materials and concepts), attachment (to material objects and to concepts), lust (sexual desires towards mental images, fantasizing), anger (also resentment, irritation, jealousy) and pride (your sense of self, attachment to an identity as the Doer of things). Try to watch them like how a cat watches a mouse hole.
What to cultivate? Love, compassion, kindness, generosity, servitude, surrender, clarity, honesty, decisiveness, devotion, dettachment, patience, steadiness, peace, openness, acceptance, alertness, reverence. Know what these words mean as feelings, as states in yourself first! then work to cultivate them. Accumulate only this wealth, no one take it away from you. No one can take away your compassion and acceptance!
3. Even more advanced still. Remember this is in addition to the above two steps.
Recognize that all phenomenon of life is impermanent. Whatever comes, goes, what is born, dies eventually. Know this like the back of your hand, intuitively, not as some form of knowledge. This links back to step 1 and 2. E.g. The acceptance of impermanence. Being steady when faced with death.
Recognize that only the Seer is permanent. Cultivate this understanding. As a practice, ask yourself "who is watching everything happen around me?" This is the Seer. Root yourself in the Seer. You can draw forth reserves of vital energy, patience, compassion, etc all those things we talked about cultivating, from the Seer. The Seer is the source of everything!
4. Final Step
So in addition to the above, recognize the Seer to be inseparable from the observed phenomenon. See it all as one. See yourself in your environment and see your environment reflected in you. In other words, see God and God alone. This will maximize the steps 1,2 and 3! You will be full with love, will do 24/7 Naam japna, etc.
Act in the world, with the understanding from Step 3 and 4.
You can access all steps right here and now but to have them activated in your life constantly you need to work through and solidify them, starting from step 1. For step 2, you need a solid step 1. For step 3, you need solid step 1 and 2 and so on. This is the only reason why they are in steps, otherwise they are all accessible at any time. It's all about building a solid base! and those are the steps to it.
Just work at it, slow and steady wins the race, meaning it requires patience, persistence and steadiness of the mind.
