In plain words
Listening, singing, remembering Viṣṇu, serving His feet, worship, salutation, service, friendship and the offering of the self.
In the end only one of them brings lasting joy. That is the offering of the self. Once it is achieved, nothing else comes near. Everything is merged in it. It is to teach that inner contentment that this Sankrānti began.
Sankrānti is what makes the Ātmatattva shine forth
Subbārāo said that Sankrānti belongs to the family. True, it is the family! The world as one family. The whole world is one family. It belongs to the whole world. It is not limited only to wife, husband, sons, daughters-in-law, grandchildren and such. This Sankrānti belongs to the whole human race. Whether they know it or not, it brings an inner feeling and gives true joy. Just as fire burns whether it is touched knowingly or unknowingly, so too, whether its greatness is recognised or not, this Sankrānti becomes an experience for everyone. It is Sankrānti that brings about a change of mind. It is Sankrānti that changes conduct. It is Sankrānti that gives a sacred radiance. It is Sankrānti that brings out into the open all the powers gathered within. It is Sankrānti that makes manifest the Ātmatattva, which had been hidden, within and unseen. Such is the boundless inner meaning this Sankrānti holds. Along with the mind, it brings Prakṛti into it as well.
The whole world is the form of the mind
There is no difference between Prakṛti and the mind. The world is the working of the mind. All of it is ‘Manomūlam idaṃ jagat’. The whole world is the very form of the mind. Without the mind there is no world. Everything is made of mind. Only when we turn such a mind towards the heart, set it on the divine and contemplate in the divine light, will the power of this mind not trouble us at all.
