Answer

In Jain practice, especially during Paryushan and while doing Ekashna, it is generally better to avoid using perfume and to use shampoo only if truly necessary.

Explanation

During Paryushan:

• Paryushan is a time of simplicity, self-control, repentance, and inner purification.
• Using perfume is usually avoided because it is connected with decoration, luxury, attraction, and attachment to the body.
• Shampoo is also best avoided if it is used for beautification or comfort. However, if needed for cleanliness or health, it may be used with restraint.

During Ekashna:

• Ekashna mainly means eating only once in the day with discipline.
• The spirit of Ekashna is to reduce bodily indulgence and increase awareness.
• Using perfume does not support the spirit of tapasya, so it is better to avoid it.
• Basic cleanliness is acceptable, but unnecessary grooming, fragrance, or beautification should be minimized.

Spiritual Understanding

In Jain Dharma, tapasya is not only about food restriction. It also means reducing attachment to comfort, appearance, taste, smell, and bodily pleasure.

So during Paryushan or Ekashna, the ideal attitude is:

• less decoration
• less comfort-seeking
• more simplicity
• more focus on the soul

Takeaway

Perfume should generally be avoided during Paryushan and Ekashna. Shampoo may be used only for genuine cleanliness or necessity, not for beautification or luxury. The main principle is to live simply and keep the mind focused on dharma.
