Commentaries and Reflections

Commentary by T Krishnamacharya:

Commentary by TKV Desikachar:

OM represents every understanding
which can be expressed by words.
Plus, everything that cannot be expressed by words.
Here, this is Īśvara, ‘that’ which knows everything.
Thus, to relate with Īśvara you start Japa using Praṇava.”

Commentary by Paul Harvey:

Bhakti Dhyānam uses Japa to build a bridge,
over the fear bringing streams of the mind.”

“The Yoga Sūtra become as if metaphysical Mantra,
when they can be an internal intonation,
as well as an external edification.”

“To realise its potential,
practice repetition of
the sacred syllable.”

Mantra is that which is reflected on.
It needs to be received from a reliable source.
In other words, from one who has reflected on Mantra
received from a person who has reflected on Mantra.”

Inspirational Quote

“Repetition of the same thought or physical action develops into a habit which, repeated frequently enough, becomes an automatic reflex.” Dr Norman Vincent Peale
