What one thinks, with that one enters into Prāṇa. Prāṇa, united with the light, together with the Self, leads to the world according to how it has been conceived.

This verse is crucial for understanding the relationship between mind and destiny. Yat-cittas — what occupies the mind, the last thought at death — determines the trajectory of prāṇa.

The prāṇa, united with tejas (cosmic light, the sun) and together with the ātman (the jīva, the individual being), nayati (conducts) to the loka (world) that has been saṅkalpita — conceived, desired, intended.

This is the doctrine of conscious death. What we think at the end of life determines our next destination. Therefore the yogī cultivates elevated thoughts constantly, so that at the crucial moment they will be ingrained.

The light (tejas) is the vehicle. The practice of luminous meditation, of visualizing divine light, prepares the yogī for the final journey. The prāṇa is the conductor, but the direction is determined by the mind.

For the practitioner: caring for thoughts is not merely mental health; it is preparation for liberation.
