In Jainism, before drinking water, it is a common practice to recite the "Namskar Mantra" (more correctly, the "Namokar Mantra" or "Navkar Mantra"). The purpose of this practice is rooted in the core Jain principles of ahimsa (non-violence) and spiritual mindfulness.

Reasons for reciting the Namokar Mantra before drinking water:

1. Ahimsa (Non-violence):

Water may contain countless microscopic living beings (jivas). By reciting the Namokar Mantra, a Jain expresses repentance for the unavoidable harm that may be caused to these living beings while drinking water. It is also a way to seek forgiveness and show compassion to all forms of life.

1. Spiritual Mindfulness:

The act of chanting the mantra helps instill awareness and gratitude. It reminds the practitioner to be conscious of their actions and their impact on other living beings, reinforcing the Jain value of minimizing harm.

1. Purification of Intent:

Reciting the Namokar Mantra helps purify the thoughts and intentions before performing an act that may inadvertently cause harm, even as simple as drinking water.

1. Seeking Blessings:

The Namokar Mantra is a prayer of obeisance to the Panch Parmesthi (five supreme beings in Jainism). By chanting it, one seeks blessings and spiritual upliftment before any activity.

Summary: Jains recite the Namokar Mantra before drinking water to practice ahimsa, bring spiritual mindfulness, purify intent, and seek blessings. This simple act is a reminder of the interconnectedness of life and the importance of minimizing harm in all actions.
