As we explore the soul, it is important to remember that this exploration will take place within nature (the body), for that is where and what we are. - B. K. S. Iyengar

Patanjali is considered the father of the yoga. On reality as far as we know, he was a yogi and polymath living around the fifth century BC, India, who collated and elaborated knowledge of the yogis’ life and practices. He wrote the Yoga Sutras, lierally a thread of aphorisms about yoga, consciousness and the human condition. Patanjali also explained the relationship between the natural world and the innermost and transcendent soul....What Patanjali said applies to me and will apply to you.

The compass is ourselves. So we are able to infer that there is a universal reality in ourselves that aligns us with a universal reality that is everywhere.

You must purge yourself before finding faults in others.
When you see a mistake in somebody else, try to find if you are making the same mistake.
This is the way to take judgment and to turn it into improvement.
Do not look at others' bodies with envy or with superiority.
All people are born with different constitutions.Never compare with others. Each one's capacities are a function of his or her internal strength.Know your capacities and continually improve upon them.
