“A person who is physically fit and
who has been cleansed by the Agni of Dhyānam
has no fear of sickness, disease, age or death.”
– T Krishnamacharya on Yoga Sūtra Chapter Three verse 2

“Another simple posture is Adho Mukha Śvan Āsana.
the next step is to try them in some sitting postures such as Mahā Mudrā.
These Bandha can also be done in the headstand.
It is easy to do Bandha in this position because the lifting,
Uḍḍīyana Bandha, and holding up, Mūla Bandha,
of Apāna to the flame is almost automatic
because now the Apāna is above the flame.
If we can do the three Bandha in these postures,
we are ready to introduce them in our Prāṇāyāma.”
– TKV Desikachar ‘The Concept, Preparation and Techniques of Bandha’ Religiousness in Yoga Chapter Fourteen Page 197

“The great yogin Yājñavalkhya said that the constant and intensive practice of Prāṇāyāma brought Prāṇa and Agni together,
and gradually the obstacle at the base of the Suṣumnā would be totally dissolved.
He gave this block the name ‘Kuṇḍali’ meaning coiled or ‘Kuṇḍalinī’ meaning ‘rolled up’ in other texts.
Kuṇḍalinī represents that which blocks access to the central energetic channel.
When this obstacle is eliminated, Prāṇa penetrates and begins to rise in the central channel.
This is the most precise description we have of the process.
This is also the most clear and coherent.”
– ‘Concerning the Cakra’ by TKV Desikachar

‘Āsana brings steadiness, health and lightness of limb.’
“For me, still to this day, one of the finest, simplest, direct and most succinct definitions on the purpose of Āsana within the processes and practices of Haṭha Yoga, is the definition offered in the Haṭha Yoga Pradīpikā Chapter 1 verse 17. It is a definition valid for any situation, or presentation, or as a response to questions from any background or level of interest around why we practice Āsana.
It can also be a springboard to discussing physiological qualities such as the relationship of Agni to the energetic qualities of health and lightness of limb. Or it can be a springboard to discussing psychological qualities such as the relationship of the Guṇa, Rajas, to mental qualities such as steadiness.”

“Bṛṃhaṇa Kriyā and Laṅghana Kriyā as expansive and contractive activities are two potentials actualised through the Breath and Āsana.
Within the practice of Āsana, Mudrā and Prāṇāyāma they are actualised through an understanding of the primary principles that inform Haṭha Yoga and Āyurveda.
The alchemical process underpinning this understanding is the relationship between the two primary principles of Prāṇa and Agni in order to influence Haṭha Yoga concepts such as Prāṇa, Apāna, Nāḍī, Cakra, Agni and Kuṇḍalinī.
In terms of Bṛṃhaṇa Kriyā and Laṅghana Kriyā, the viniyoga of Bṛṃhaṇa affects a dispersion of Agni from the core to the periphery and the viniyoga of Laṅghana affects a withdrawal of Agni from the periphery to the core.
Understanding the application of this particular process facilitates access, through the Vīna Daṇḍa (spine), Prāṇa and Agni, to energising, cleansing and aligning potentials in the practice of Āsana, Mudrā and Prāṇāyāma.”

“Cikitsā Krama is to gather dissipated Agni.
Rakṣaṇa Krama is to conserve gathered Agni.
Śikṣaṇa Krama is to intensify conserved Agni.”

“Compare the techniques and functions and applications for Śītalī and Sītkārī.
Especially with regard to their effects on Agni.”
