Lent is a religious observance that is traditionally practiced by Christians as a period of repentance, self-reflection, and preparation for Easter.
If you are non Christian you can choose to observe Lent as well by using it as a time for:-:
Self-reflection: You will find great value in taking some time to reflect on your life and make positive changes.
Fasting and abstinence – Challenge yourself to give up something as this will help you to have discipline and self control.
Simply put, it means you stop eating completely, or almost completely, for a certain stretch of time. A fast usually lasts from 12 to 24 hours, but some types continue for days at a time. In some cases, you may be allowed water, tea, and coffee or even a small amount of food during the “fasting period.
Spirituality and mindfulness:- find value in engaging in spiritual or mindfulness practices during this time to improve your mental and emotional well-being. Mindfulness is a type of meditation in which you focus on being intensely aware of what you’re sensing and feeling in the moment, without interpretation or judgment. Practicing mindfulness involves breathing methods, guided imagery, and other practices to relax the body and mind and help reduce stress.
