I am guessing that Prashanth meant Atma-Samyama Yoga which includes the Dharana-Dhyana-Samadhi, the last 3 practices of the 8 pillars of Astanga Yoga. The effort to control the senses is Pratyahara which is the 4th practice.

I think for devotion or bhakti, unconditional faith is essential and with effort comes surrender/control of the senses (pratyahara) and the mind which means giving away the power of attorney to the paramatman.
