“Then, he has also some views on Dhyāna.
Since Dhyāna is a characteristic of mind,
and since the mind is limited to form,
Deśa, or the object of meditation,
must be Saguṇa and not Nirguṇa.

Ordinary people need certain forms,
certain visualisations, for Dhyāna,
so any Dhyāna which is Nirguṇa is only Vikalpa.”

– TKV Desikachar from lectures on ‘The Yoga of T Krishnamacharya’,
given at Zinal, Switzerland 1981.
