Answer

In Jain Dharma, it is not fixed that after death a soul “usually” goes to Dev Lok, Narak, or Tiryanch gati. A soul can be reborn in any of the four gatis:

• Deva gati
• Narak gati
• Tiryanch gati
• Manushya gati

The next birth depends on the karma the soul has bound. And yes, human birth is considered very rare and very precious in Jainism.

Explanation

Your statement is close to Jain teaching, but it needs one correction:

• After death, the soul does not go randomly.
• It goes according to its karma and mental state at the time of death.
• Human gati is not impossible, but it is considered durlabh — very difficult to प्राप्त.

Jain tradition teaches that human birth is especially valuable because only in human life can a soul:

• understand dharma properly,
• practice vows and restraint,
• do deep sādhanā,
• and progress toward moksha.

Spiritual Understanding

Jain Dharma emphasizes that the human state is rare because it gives the best opportunity for spiritual liberation.

That is why human birth is seen as a great blessing:

• It is the best place to practice ahiṁsā
• It allows self-discipline and detachment
• It gives the chance to stop karmic bondage
• It is the doorway to moksha

So, while many souls may be born in lower or higher gatis according to karma, human birth is especially important and rare.

Takeaway

A Jain way to remember it is:

• Birth after death depends on karma
• All four gatis are possible
• Human birth is rare and spiritually precious
• From human life, liberation becomes possible
