Answer

In Jain and Indian intellectual tradition, Avadhān means the ability to keep attention on multiple things at the same time with deep concentration and memory.

Śatāvadhān means performing Avadhān with 100 simultaneous tasks or questions.

So, the simple difference is:

• Avadhān = the general art of intense concentration, memory, and multi-task attention.
• Śatāvadhān = a special form of Avadhān involving 100 avadhāns or challenges at once.

Explanation

The word Avadhān comes from the idea of focused attention. In such performances, a person may be asked to remember words, numbers, poetry, questions, sequences, or other details, and later recall or respond to them correctly.

Śatāvadhān is a higher and more difficult form. The word śata means “hundred.” Therefore, Śatāvadhān means handling one hundred streams of attention or tasks.

For example:

• If a scholar answers or remembers several questions with concentration, it may be called Avadhān.
• If the scholar successfully manages 100 different questions or tasks, it is called Śatāvadhān.

Spiritual Understanding

In Jain Dharma, such abilities are respected because they show the power of:

• Ekāgratā — one-pointed concentration
• Smṛti — memory
• Manobal — strength of mind
• Saṃyam — inner discipline

However, Jain Dharma also teaches that intellectual brilliance is not the final goal. The higher purpose of concentration is to move toward samyag darshan, samyag jnan, samyag charitra, and ultimately liberation.

Takeaway

Avadhān is the general discipline of extraordinary attention and memory. Śatāvadhān is a specific and advanced form where one manages 100 tasks or questions at once.
