In Jainism, Ekashna (also spelled Ekashana) refers to a disciplined practice of single-pointed meditation or focused contemplation on a specific spiritual theme or truth. It is an important practice for developing concentration, self-discipline, and spiritual insight. Here are the detailed steps of Ekashna in simple and easy-to-understand terms:

1. Preparation (Sthiti/Sthapana)

- Choose a quiet and clean place where you will not be disturbed. - Sit in a comfortable and stable posture, such as Padmasana (lotus position) or any cross-legged posture that allows focus and stillness. - Keep your body relaxed but alert, maintaining a straight spine.

1. Select the Object of Meditation (Vishaya)

- Decide on a single inspirational or spiritual theme to focus on. - Common objects include the qualities of the Tirthankaras, the nature of the soul (jiva), the concepts of non-attachment (aparigraha), or the five great vows (mahavratas).

1. Focus Attention (Ekagrata)

- Direct your full attention on the chosen object without allowing the mind to wander. - Avoid distractions, and gently bring back your focus whenever it drifts away.

1. Contemplation (Chintan)

- Reflect deeply on the essence and meaning of the object of meditation. - For example, if meditating on non-attachment, contemplate how attachment causes suffering and how its removal leads to liberation.

1. Maintain Mental Stillness (Nirvikalpaka Samadhi)

- Gradually, your mind becomes calm, free from fluctuating thoughts. - The focus deepens into a state of peaceful, one-pointed awareness.

1. Duration and Consistency

- Practice for a fixed period daily, starting with short intervals and gradually increasing. - Regularity is key to progress.

1. Ending the Session

- Slowly withdraw your focus and remain quiet for a moment. - Open your eyes gently and spend a few moments in gratitude.

Spiritual Benefits:

• Ekashna strengthens concentration (dhyanasthiti).
• It purifies the mind by removing distractions and impurities.
• It prepares the aspirant for higher stages of meditation (Samadhi).
• Ultimately, it fosters insight into the true nature of the self and aids in liberation.

These steps are consistent with Jain texts on meditation such as those found in the Samayasāra of Acharya Kundakunda and the meditation instructions in the Yogaśāstra of Hemachandra.
