“The target of Yoga is ‘Svatantra’ 
which means to discover our own technique.
‘Sva’ means self and ‘Tantra’ means technique.
The techniques are in oneself and we must discover them;
if not we will depend on others.
This is ‘Svatantra’.”
– TKV Desikachar

“The practice of Bhakti Dhyānam outlined in the Yoga Sūtra Chapter One
can utilise either Veda Mantra or Tantra Mantra.
The Veda focus is one of external harmony with the forces of nature (Tri Guṇa) and
the Tantra focus is one of internal empowerment within the forces of nature (Tri Guṇa).”
