While meditating upon Narayana - the lotus that he holds in his right hand - consider it as the Kundalini - the thousand petal led lotus with its stem at his feet and rising through the chakras in the body. This is total trust and awakening that we are in the safe hands of the supreme. This is surrendering in Bhakti.
Watching the breath in Prana-Yama Yoga is practising ‘ Salshi- Bhava’ - being a witness to our own thoughts.
