Of all the 12 universal laws, the law of attraction undoubtedly gets the most attention. Simply put, this spiritual principle suggests that like attracts like and positive thinking can usher in a more positive reality.

Lao Tzu, an ancient Chinese philosopher, once said: "Watch your thoughts, they become your words; watch your words, they become your actions; watch your actions, they become your habits; watch your habits, they become your character; watch your character, it becomes your destiny."

The idea that we attract what we put out has clearly been around since ancient times, and many credit Buddha with first introducing this notion to the world.

Working with the law of attraction to manifest your dreams may sound straightforward, but it actually involves careful intention, action, and a degree of surrender.

Like attracts like—even if we're not conscious of it. We're always "attracting" positivity or negativity based on the energy we're putting out ourselves.

"We are all like magnets, both reflecting and attracting what we hold in our thoughts," explains spiritual author Shannon Kaiser.

This principle suggests that empty space cannot truly exist, and always needs to be filled by something. As such, it's important to make space for positive change in your life by clearing out negativity.

Perfecting the present moment is the third and last aspect of the law of attraction.

It tells us that there will always be things to be unhappy about if you look for them, but rather than dwelling on things that are going wrong, finding ways to make things better is fundamental to shifting your reality into one that attracts what you desire.

That's not to say you can't acknowledge negativity or feel emotions related to it. (That gets into spiritual bypassing or toxic positivity territory.) Rather, it's about doing what you can at the moment to improve any negative situation and letting the rest go.

Of course, positive thinking and belief alone won't make your dreams come true. You need to put in the work, too!

This means living in alignment with your goals and taking the necessary steps to bring them to life.

For example, if your goal is to run a marathon in under four hours, you still need to put in the training and treat your body right in the months leading up to the race. From there, layering on some positive mantras and visualizations can further reinforce your goal with the universe.

Anyone prone to worry should also know that the law of attraction isn't a punishment. As Kaiser notes, "When people first learn and start to practice this law, sometimes they get worried that if they have bad thoughts or low vibrations, they can somehow mess up their life." Nobody is perfect, and we can use the law as "a mirror of our own mindset and self-worth" when we're working through a challenging phase.

And always remember that at a certain point in manifestation, "it's important to surrender and let the Universe take the wheel," Richardson adds. "Opportunities, people, and resources can show up out of the blue, so be open to them." Things may not play out how you imagined (in fact, they probably won't) and that's OK.

The first step in using the law of attraction to welcome more love into your life is to notice how you could be subconsciously resisting it.

For example, Kaiser says that "if the universe keeps bringing you unavailable people, this could indicate something within you is still unavailable."

When working with the law of attraction in your professional life, it's important to get specific about what you want.

Write down your career goals using concrete statements like "I want to work with like-minded people who support my ideas" or "I make X amount of money in X city." And of course, action is important here. If you want that promotion, ask yourself, "What would the 'promoted-me' do?"

Financial fears are sensitive and valid, and it takes a lot of unlearning to create a healthy relationship with financial abundance.

With money, it's especially easy to fall into a scarcity mindset. Instead, try your best to focus on what you already have rather than what you lack. One mantra Kaiser uses for this is "Abundance flows through me so I can happily give."
