More information on the figures for those who might be interested. The central figure is Lama Tzongkhapa in the characteristic yellow Pandit's hat.
The main meditational deities (yidams) underneath Lama Tzongkhapa are (l to r) Yamantaka, Guyasamaja, Chakrasamvara and Hevajra. As you move down you see the deities of action tantra, various bodhisattvas, and near the bottom dharma protectors such as Kalarupa, Mahakala and Palden Lhamo.
The figures at the top part are not so clear but two of them look like Mahasiddhas Tilopa and Naropa.
In order to ensure my mind never comes under the power of the self-cherishing attitude,
I must obtain control over my own mind.
Therefore, amongst all empowerments, the empowerment that gives me control over my mind is the best,
and I have received the most profound empowerment with this teaching.
