Yes, in the practice of Samayik (a meditative and spiritual practice in Jainism aimed at achieving equanimity), it is customary and important to recite the full Navkar Mantra (Namokar Mantra) as a foundational prayer. The recitation of the Navkar Mantra is part of the rituals and helps to focus the mind, purify thoughts, and pay respect to the Panch Parmeshthi (the five supreme beings in Jainism).

Kaussag refers to the practice of meditative standing or sitting in a posture of stillness, often combined with the recitation of prayers for repentance, forgiveness, and reflection. During Samayik, performing Naukar Kaussag means standing or sitting in kaussag and reciting the full Navkar Mantra with concentration and reverence.

In summary:

• During Samayik, you should recite the full Navkar Mantra (Naukar Mantra).
• Performing Kaussag with the Navkar Mantra is a part of the Samayik ritual.
• This practice helps in achieving inner peace and spiritual upliftment.

If you follow a specific Jain sect (Shwetambar or Digambar), there may be slight variations in the procedure, but the essence remains the same.
