3 things: Boredom, Prayer, Offering.
Boredom is actually crucial for motivation. You want to spend at least 10 minutes per day being completely bored. No thoughts, no TV, no internet, no music, nothing. Just sit in a silent room with nothing to look at, without thinking about anything.
Your brain works on motivation, and it can run out of it, especially if it is over simulated and constantly working with thoughts, visuals, sounds…ect.
So spend some time per day in complete boredom so brain rests.
Prayer is of course crucial in divine meditation. It can be as simple as repeating words in your head over and over. Hindu repeat “Namah Shivaya” for example. If you cant memorize some long prayer to some God, repeating few words over and over works too. Now, you should also mention your wishes to God in a prayer, obviously.
Offering is basically crucial in a divine relationship. There are many people who pray to God but dont give offerings, which is stupid. Its like coming to someone and saying “Do everything for me while I wont do anything for you”. It could even insult Gods to pray that way to them. Offerings usually include food, gold, silver…ect. Some people burn food in a fire as an offering, and that is good, generally, just as is giving food to Earth, or water… or leaving food on altar to offer it to surrounding air.
I think these 3 are crucial for gaining motivation in life. There could be more, but these are ways I find best.
